Trang 9Thank you once again, Microsoft, for a great release of Exchange Server This is now the seventh major release of the well-known premiere messaging system In this release, we can see the effort and the ingenuity come together in solving customer problems to create a truly superior product Congratulations!
As the team that is working on this book completes the final steps required to send it to the printer, I continue to bring some real-world expertise into the content I have deployed several Exchange Server 2013 infrastructures to date, but this product is so vast and so broad that I con-tinue to find design options, best practices, and architecture recommendations on a daily basis I’m pretty sure that I will be updating the content up to the last minute!
When I was approached to take on this book, several months before Exchange Server 2013 was about to release to manufacturing, my reaction was, “What about Jim?” Jim McBee, having
authored three previous editions of this book, has been the pillar of the Mastering Exchange Server series and an inspiring role model in my own Exchange Server consulting career I con-
sider it to be a true honor to take over for Jim McBee as the lead author for this book, and I hope that this edition has adequately followed through on his tradition
Throughout the book, I have tried to keep the tone and language similar to what was used in the previous editions of this book, so if you are familiar with Jim’s writing style, you should find comfort in these pages In addition, I have removed some of the introductory technical informa-tion from previous editions, to reflect the depth of initial experience of the readers
Taking on the responsibility of a 900+ -page manual is no simple task and not one that can be undertaken by only one person Along the way, I have invited several contributors to this effort Their knowledge and expertise have added incredible value to this book Having written any-where from several paragraphs to complete chapters, Chris Crandall, Devin Ganger, Mahmoud Magdy, Adam Micelli, Bob Reinsch, Jeffrey Rosen, and Michael Smith are Exchange Server gurus who have provided key content for this book Some of this has been outside my areas of expertise and a great contribution to this effort Thank you!
There is also a man who has kept us all honest and has been the gatekeeper for technical accuracy in this book, and he has helped revise a couple of chapters more substantially J Peter Bruzzese agreed to take on the responsibility of technical reviewer for this book and has done a formidable job When I received a chapter back from Peter with only very few red marks, I con-sidered it an achievement! Peter, thank you!
The great folks at Wiley have been patient beyond belief when it comes to deadlines, content, and outline changes as well as our ever-changing list of contributors They include acquisitions editor Mariann Barsolo, developmental editor Candace Cunningham, and production editor Dassi Zeidel
Along the way, several Exchange Server experts have answered my questions, calmed my nerves, and listened to my rants about configuration frustrations I would like to acknowledge them, even if some of them answered my questions without knowing it They include Paul Adare, David Espinosa, Stan Reimer, Paul Robichaux, Scott Schnoll, Ross Smith, Greg Taylor, and Brian Tirch And a big thank-you goes to Corey Hynes and Kim Frank for providing me with some very useful virtual server environments
Trang 10I would also like to acknowledge those who have helped me in my own Exchange Server path, from Sandra Ford, who hired me to teach my first Exchange Server 5.0 course, to Ken Rosen, who inspired me to write my first course on Exchange Server 2003, to Jennifer Morrison, who pushed to hire me on my first large Microsoft project Thank you!
I would also like to thank my business partner and friend, Jonathan Long, for doing the work
I was supposed to be doing when I was writing this book and for supporting me through this latest writing effort
And a special acknowledgement to those in my daily life, my father, Elie Elfassy; my uncle, Leon Elfassy; my sister, Celine Elfassy; and my father-in-law, Sam Katz: thank you for always being supportive of all my endeavors

Trang 27Thank you for purchasing (or considering the purchase of) Mastering Exchange Server 2013;
this is the latest in a series of Mastering Exchange Server books that have helped thousands of readers to better understand Microsoft’s excellent messaging system Along the way, we hope that this series of books has made you a better administrator and allowed you to support your organizations to the best of your abilities
When we started planning the outline of this book more than a year before its release, Exchange Server 2013 appeared to be simply a minor series of improvements over Exchange Server 2010 Of course, the further we explored the product, the more we found that was not the case Many of the improvements in Exchange Server 2013 were major improvements (such
as DAG management) and sometimes even complete rewrites (such as in the case of the Client Access server role) of how the product worked previously
Another challenge then presented itself The market penetration of Exchange Server 2010 was fairly dominant, but we found that many organizations still run Exchange Server 2007 Though increasingly smaller, a percentage of Exchange Server customers are still using Exchange Server
2003 Thus, we needed to explain the differences for not only Exchange Server 2010 tors but also for the Exchange Server 2007 and even Exchange Server 2003 administrators
administra-We took a step back and looked at the previous editions of the book to figure out how much
of the previous material was still relevant Some of the material from the Exchange Server 2010 book is still relevant but needed updating Some required completely new chapters to cover new technologies introduced in Exchange Server 2013 or technologies that have since taken on more importance in deployments and management We faced the challenge of explaining two management interfaces, Exchange Management Shell and Exchange Admin Center, as well as describing the new roles and features
We started working with the Exchange Server 2013 code more than a year before we expected
to release the book Much of the book was written using the RTM code that was first made available in October 2012, but as we continued writing the book, we made updates to changes introduced in Cumulative Update 1 and Cumulative Update 2 So, you can safely assume when reading this book that it is based on the latest bits of Exchange Server 2013 that released in late summer 2013 In writing this book, we had a few goals for the book and the knowledge we wanted to impart to the reader:
◆ We wanted to provide an appropriate context for the role of messaging services in an nization, outlining the primary skills required by an Exchange Server administrator
orga-◆ We wanted the reader to feel comfortable when approaching an Exchange Server ment of any size The content in this book can assist administrators of small companies with only one server, as well as administrators who handle large Exchange Server farms
environ-◆ We wanted the skills and tasks covered in this book to be applicable to 80 percent of all organizations running Exchange Server
◆ We wanted the book to educate not only “new to product” administrators but also those
“new to version” administrators who are upgrading from a previous version
Trang 28ensur-Microsoft listened to the advice of many of its customers, its internal consultants at ensur-Microsoft Consulting Services (MCS), Microsoft Certified Systems Engineers (MCSEs), Most Valuable Professionals (MVPs), Microsoft Certified Solutions Masters (MCSMs), and Microsoft Certified Trainers (MCTs) to find out what was missing from earlier versions of the product and what organizations’ needs were Much of this work started even before Exchange Server 2013 was released.
Major Changes in Exchange Server 2013
This book covers the many changes in Exchange Server 2013 in detail, but we thought we would give you a little sample of what is to come in the chapters As you can imagine, the changes are once again significant, considering the tremendous effort that Microsoft sinks into the Exchange Server line of products Exchange Server is a significant generator of revenue for Microsoft and
is also a foundational service for Office 365 Microsoft has every reason to continue improving this most impressive market leader of email and collaboration services
The primary changes in Exchange Server 2013 since the latest release (Exchange Server 2010) have come in the following areas:
◆ Replacement of the Exchange Management Console by the web-based console Exchange Admin Center
◆ Integration of Transport services into the Client Access and Mailbox server roles and sequent removal of the Hub Transport server role
sub-◆ Integration of Unified Messaging services into the Client Access and Mailbox server roles and subsequent removal of the Unified Messaging server role
◆ Reconfiguration of public folders to be stored in mailbox databases within a public folder mailbox
◆ Improved integration with SharePoint Server 2013 and Lync Server 2013, including options for archiving Lync conversations in Exchange Server
◆ Completely rewritten Information Store processes, now named the Managed Store
◆ Significant improvement in database maintenance, database availability group ment, and overall site resiliency functionalities
manage-◆ Significant improvement in Transport rules, mainly through the implementation of the new Data Loss Prevention (DLP) policies
Of course, many more changes have been introduced in Exchange Server 2013, but the ceding list stands out to us as the most noteworthy improvements Chapter 2, “Introducing the Changes in Exchange Server 2013,” contains an exhaustive list of all significant changes, as well
pre-as changes since specific versions of Exchange Server (for example, Exchange Server 2003 versus Exchange Server 2013)

How This Book Is Organized
This book consists of 25 chapters, divided into five broad parts As you proceed through the book, you’ll move from general concepts to increasingly detailed descriptions of hands-on
implementation
This book won’t work well for practitioners of the time-worn ritual of chapter hopping
Although some readers may benefit from reading one or two chapters, we recommend that you read most of the book in order Even if you have experience as an Exchange Server administra-tor, we recommend that you do not skip any chapter, because they all provide new information since the previous iterations of Exchange Server Only if you already have considerable experi-ence with these products should you jump to the chapter that discusses in detail the informa-tion you are looking for
If you are like most administrators, though, you like to get your hands on the software and actually see things working Having a working system also helps many people as they read a book or learn about a new piece of software because this lets them test new skills as they learn them If this sounds like you, then start with Chapter 7, “Exchange Server 2013 Quick Start
Guide.” This chapter will take you briefly through some of the things you need to know to get Exchange Server running, but not in a lot of detail As long as you’re not planning to put your quickie server into production immediately, there should be no harm done Before you put it into production, though, we strongly suggest that you explore other parts of this book Here’s a guide to what’s in each chapter
Part 1: Exchange Fundamentals
This part of the book focuses on concepts and features of Microsoft’s Windows Server 2012,
Exchange Server 2013, and some of the fundamentals of operating a modern client/server email system
Chapter 1, “Putting Exchange Server 2013 in Context,” is for those administrators who have been handed an Exchange Server organization but who have never managed a previous ver-sion of Exchange Server or even another mail system This will give you some of the basic information and background to help you get started managing Exchange Server and, hope-fully, a little history and perspective
Chapter 2, “Introducing the Changes in Exchange Server 2013,” introduces the new features
of Exchange Server 2013 as contrasted with previous versions
Chapter 3, “Understanding Availability, Recovery, and Compliance,” helps even experienced administrators navigate some of the new hurdles that Exchange Server administrators must overcome, including providing better system availability, site resiliency, backup and restora-
tion plans, and legal compliance This chapter does not cover database availability groups in
detail; instead, that information is covered in Chapter 20, “Creating and Managing Database Availability Groups.”
Chapter 4, “Virtualizing Exchange Server 2013,” helps you decide whether you should alize some percentage of your servers, as many organizations are doing
virtu-Chapter 5, “Introduction to PowerShell and the Exchange Management Shell,” focuses on and uses examples of features that are enabled in PowerShell through the Exchange Server
Trang 30XXVIII | INTRODUCTION
2013 management extensions for PowerShell All administrators should have at least a basic familiarity with the Exchange Management Shell extensions for PowerShell even if you rarely use them
Chapter 6, “Understanding the Exchange Autodiscover Process,” helps you to come up to speed on the inner workings of the magic voodoo that is Autodiscover, a feature that greatly simplifies the configuration of both internal and external clients
Part 2: Getting Exchange Server Running
This section of the book is devoted to topics related to meeting the prerequisites for Exchange Server and getting Exchange Server installed correctly the first time While installing Exchange Server correctly is not rocket science, getting everything right the first time will greatly simplify your deployment
Chapter 7, “Exchange Server 2013 Quick Start Guide,” is where everyone likes to jump right
in and install the software This chapter will help you quickly get a single server up and ning for your test and lab environment While you should not deploy an entire enterprise based on the content of this one chapter, it will help you get started quickly
run-Chapter 8, “Understanding Server Roles and Configurations,” covers the primary services that run on the two Exchange Server roles: Mailbox server and Client Access server It also covers the architecture of communications between the roles
Chapter 9, “Exchange Server 2013 Requirements,” guides you through the requirements taining to Windows Server, Active Directory, and previous versions of Exchange Server) that you must meet in order to successfully deploy Exchange Server 2013
(per-Chapter 10, “Installing Exchange Server 2013,” takes you through both the graphical user interface and the command-line setup for installing Exchange Server 2013
Chapter 11, “Upgrades and Migrations to Exchange Server 2013 or Office 365,” helps you decide on the right migration or transition approach for your organization It recommends steps to take to upgrade your organization from Exchange Server 2007 or 2010 to Exchange Server 2013 or to Office 365 Also included in this chapter are recommendations for migration phases and hybrid coexistence with Office 365
Part 3: Recipient Administration
Recipient administration generally ends up being the most time-consuming portion of Exchange Server administration Recipient administration includes creating and managing mailboxes, managing mail groups, creating and managing contacts, and administering public folders.Chapter 12, “Management Permissions and Role-based Access Control,” introduces one
of the most powerful features of Exchange Server 2013, Role-based Access Control, which enables extremely detailed delegation of permissions for all Exchange Server administrative tasks This feature will be of great value to large organizations
Chapter 13, “Basics of Recipient Management,” introduces you to some concepts you should consider before you start creating users, including how email addresses are generated and how recipients should be configured
Trang 31INTRODUCTION | XXIX
Chapter 14, “Managing Mailboxes and Mailbox Content,” is at the core of most Exchange Server administrators’ jobs since the mailboxes represent our direct customer (the end user) This chapter introduces the concepts of managing mailboxes, mailbox data (such as personal archives), and mailbox data retention
Chapter 15, “Managing Mail-enabled Groups, Mail-enabled Users, and Mail-enabled
Contacts,” covers management of these objects, including creating them, assigning email addresses, securing groups, and allowing for self-service management of groups, and it
offers guidelines for creating contacts
Chapter 16, “Managing Resource Mailboxes,” discusses a key task for most messaging
administrators A resource can be either a room (such as a conference room) or a piece of
equipment (such as an overhead projector) Exchange Server 2013 makes it easy to allow
users to view the availability of resources and request the use of these resources from within Outlook or Outlook Web App
Chapter 17, “Managing Modern Public Folders,” introduces you to the new public folder age and management features in Exchange Server 2013 Although public folders are being deemphasized in many organizations, other organizations still have massive quantities of data stored in them Microsoft has reinvented public folders in this latest release of Exchange Server
stor-Chapter 18, “Managing Archiving and Compliance,” covers not only the overall concepts of archiving and how the rest of the industry handles archiving but also the exciting archival and retention features
Part 4: Server Administration
Although recipient administration is important, administrators must not forget their sibilities to properly set up the Exchange server and maintain it This section helps introduce you to the configuration tasks and maintenance necessary for some of the Exchange Server 2013 roles as well as safely connecting your organization to the Internet
respon-Chapter 19, “Creating and Managing Mailbox Databases,” helps familiarize you with the
changes in Exchange Server 2013 with respect to mailbox database, storage, and basic
siz-ing requirements Many excitsiz-ing changes have been made to support large databases and to allow Exchange Server to scale to support more simultaneous users
Chapter 20, “Creating and Managing Database Availability Groups,” is a key chapter in this book that will affect all administrators from small to large organizations Exchange Server
2013 relies heavily on Windows Failover Clustering for its site resilience and high availability functionalities This chapter covers the implementation and management of high availability solutions
Chapter 21, “Understanding the Client Access Server,” introduces you to the critical Client Access server role and the components running on the Client Access server
Chapter 22, “Managing Connectivity with Transport Services,” brings you up to speed on the Transport services that run on the Mailbox and Client Access server roles This chapter dis-cusses mail flow and the transport pipeline in detail
Trang 32XXX | INTRODUCTION
Chapter 23, “Managing Transport, Data Loss Prevention, and Journaling Rules,” shows you how to implement a feature set that was first introduced in Exchange Server 2007 but has since been greatly improved: the transport rule feature This chapter also discusses message journaling and the new Data Loss Prevention policies
Part 5: Troubleshooting and Operating
Troubleshooting and keeping a proper eye on your Exchange servers’ health are often
neglected tasks You may not look at your Exchange servers until there is an actual problem In this part we discuss some tips and tools that will help you proactively manage your Exchange Server environment, ensuring that you can track down problems as well as restore any
potential lost data
Chapter 24, “Troubleshooting Exchange Server 2013,” introduces you not only to shooting the various components of Exchange Server 2013 but also to good troubleshoot-ing techniques This chapter also includes a discussion of some of the Exchange Server
trouble-2013 built-in tools, such as the Exchange Management Shell test cmdlets and the Remote Connectivity Analyzer
Chapter 25, “Backing Up and Restoring Exchange Server,” includes discussions on ing a backup plan for your Exchange Server 2013 servers as well as how to implement appro-priate backup solutions for Exchange Server configuration, databases, logs, and any other relevant information
develop-Conventions Used in This Book
We use the code-continuation character on PowerShell commands to indicate that the line of text
is part of a previous command line
Many of the screen captures in this book have been taken from lab and test environments However, sometimes you will see screen-captures that came from an actual working environ-ment We have obscured any information that would identify those environments
Any examples that include IP addresses have had the IP addresses changed to private IP addresses even if we are referring to Internet addresses
Remember, Exchange Server is designed to help your organization do what it does better, more efficiently, and with greater productivity Have fun, be productive, and prosper!

Trang 35contains If there’s a problem with email, it affects users’ confidence in their ability to do their jobs—and their confidence in IT.
Microsoft’s Exchange Server products play a key role in electronic messaging, including email This chapter is a high-level primer on Exchange Server–based email administration and good administration practices, and it prepares you to put Exchange Server 2013 into the proper context An experienced email administrator may want to proceed to more-technical chapters However, if you are new to the job or need a refresher, or maybe you just want to put email services back into perspective, this chapter is for you!
In this chapter, you will learn to:
◆ Understand email fundamentals
◆ Identify email-administration duties
Billions of emails are sent every day (more than 500 billion worldwide, according to Research firm The Radicati Group) That’s a lot of email messages, on a lot of servers—many of them Exchange servers
Sure, sending simple text email and file attachments is the most basic function, but email systems (the client and/or the server) may also perform the following important functions:
Trang 364 | CHAPTER 1 PUTTING EXCHANGE SERVER 2013 IN CONTEXT
◆ Act as a personal information manager, providing storage for and access to personal dars, personal contacts, to-do and task lists, personal journals, and chat histories
calen-◆ Provide the user with a single “point of entry” for multiple types of information, such as voicemail, faxes, and electronic forms
◆ Provide shared calendars, departmental contacts, and other shared information
◆ Provide notifications of workflow processes, such as finance/accounting activities, IT events (server status information), and more
◆ Archive important attachments, text messages, and many other types of information
◆ Allow users to access their “email data” through a variety of means, including clients running on Windows computers, Apple computers, Unix systems, web browsers, mobile phones, and even a regular telephone
◆ Perform records management and enable long-term storage of important information or information that must be archived
◆ Enable near-time communication of sales and support information with vendors and customers
These are just a few of the types of things that an email system may provide to the end user either via the client interface or as a result of some function running on the server
How Messaging Servers Work
At the core of any messaging system, you will find a common set of basic functions These functions may be implemented in different ways depending on the vendor or even the version
of the product Exchange Server has evolved dramatically over the past 18 years, and its current architecture is almost nothing like Exchange Server 4.0 from 1996 Common components of most messaging systems include the following:
◆ A message transport system that moves messages from one place to another Examples include the Simple Mail Transport Protocol (SMTP)
◆ A message storage system that stores messages until a user can read or retrieve them Messages may be stored in a client/server database, a shared file database, or even in indi-vidual files
◆ A directory service that allows a user to look up information about the mail system’s users, such as a user’s email address
◆ A client access interface on the server that allows the clients to get to their stored messages This might include a web interface, a client/server interface, or the Post Office Protocol (POP)
◆ The client program that allows users to read their mail, send mail, and access the tory This may include Outlook, Outlook Web App, and a mobile device such as a Windows Phone, an iPhone, or an Android device
direc-Working in tandem with real-time interactive technologies, electronic messaging systems have already produced a set of imaginative business, entertainment, and educational
applications with high payoff potential All of this action, of course, accelerates the demand for electronic messaging capabilities and services
Trang 37WHAT IS EXCHANGE SERVER? | 5
Most organizations that deploy an email system usually deploy additional components from their email software vendor or third parties that extend the capabilities of the email system or provide required services These include the following:
◆ Integration with existing phone systems or enterprise voice deployments to pull voice sages into the mailbox
mes-◆ Message-hygiene systems that help reduce the likelihood of a malicious or inappropriate message being delivered to a user
◆ Backup and recovery, disaster recovery, and business continuity solutions
◆ Message archival software to allow for the long-term retention and indexing of email data
◆ Electronic forms routing software that may integrate with accounting, order entry, or other line-of-business applications
◆ Mail gateways to allow differing mobile devices, such as BlackBerry devices, to access the mail server, along with native access through Exchange ActiveSync
◆ Email security systems that improve the security of email data either while being ferred or while sitting in the user’s mailbox
trans-◆ A link load balancer to balance the load between multiple Internet-facing servers or nal servers
inter-What Is Exchange Server?
In its simplest form, Exchange Server provides the underlying infrastructure necessary to run
a messaging system Exchange Server provides the database to store email data, the transport infrastructure to move the email data from one place to another, and the access points to access email data via a number of different clients
However, Exchange Server, when used with other clients such as Outlook or Outlook
Web App, turns the “mailbox” into a point of storage for personal information management such as your calendar, contacts, task lists, and any file type Users can share some or all of
this information in their own mailbox with other users on the message system and start to
collaborate
The Outlook and Outlook Web App clients also provide access to public folders Public
folders look like regular mail folders in your mailbox, except that they are in an area where
they can be shared by all users within the organization A folder can have specialized forms associated with it to allow the sharing of contacts, calendar entries, or even other specialized forms Further, each public folder can be secured so that only certain users can view or modify data in that folder
The Unified Messaging features in Exchange Server 2013 further extend the functions of
Exchange Server in your organization by allowing your Exchange Server infrastructure to also act as your voicemail system and direct voicemails and missed-call notifications automatically
to the user’s mailbox
While integrated voicemail solutions are nothing new for Exchange Server customers,
Microsoft is now providing these capabilities out of the box rather than relying on third-party products
Trang 386 | CHAPTER 1 PUTTING EXCHANGE SERVER 2013 IN CONTEXT
Exchange Server 2013 tightens the integration of collaborative tools in its integration with Lync Server 2013, the Lync client, and the Lync Mobile client Lync provides a core set of SIP-based enterprise voice capabilities that allows it to act as a PBX in many cases With Exchange Server, Lync, Outlook, and the Lync client, users enjoyed full Unified Messaging with software-based telephony from their computer, including the new voicemail and missed-call notification provided by Exchange Server and Outlook Furthermore, Lync could log chat and instant-message conversation logs to a folder in the user’s mailbox Exchange Server 2013 further pushes this integration, embedding basic IM and presence capabilities into the Outlook Web App premium experience
The capabilities of the client can be extended with third-party tools and forms-routing software so that electronic forms can be routed through email to users’ desktops
About Messaging Services
Electronic messaging is now far more than email Together, Exchange Server 2013 and its clients perform a variety of messaging-based functions These functions include email, unified messaging, message routing, scheduling, and support for several types of custom applications Together these features are called messaging services
Many Modes of Access
For years, the only way to access your email system was to use a Windows, Macintosh, or based client and access the email system directly In the case of Outlook and Exchange Server, this access was originally in the form of a MAPI client directly against the Exchange server As Exchange Server has evolved, it has included support for the POP3 and IMAP4 protocols, then web-based email access, and finally mobile device access Exchange Server 2013 doesn’t offer any radically new modes of mailbox access as Exchange Server 2007 did, but it does provide ongoing support and refinement of existing Exchange Server 2007 technologies, such as Exchange Web Services, that can provide additional mechanisms for accessing data in mailboxes and a move away from RPC in client connectivity in favor of RPC over HTTPs, also known as Outlook Anywhere
Unix-Outlook Web App (OWA) has evolved quickly and, in Exchange Server 2013, bears almost no resemblance to the original version found in Exchange Server 5.0 in terms of features, functions, and the look of the interface Exchange Server 2013 OWA is even a radical step beyond Exchange Server 2010 It also expands the previous option configuration experience of the Exchange Control Panel (ECP), which gives users a much greater degree of control over their mailbox, contacts, and group memberships ECP is now built into the Outlook Web App interface Using ECP, end users can create and join distribution groups (where permissions have been assigned), track their own messages throughout the organization, and perform other functions that previously required help-desk or IT professional intervention Another significant feature
of Outlook Web App is the ability to use the web-based interface when working offline and completely disconnected from the network
With Exchange Server 2013, Exchange ActiveSync (EAS) continues to offer significant partnerships with and control over mobile devices Many vendors have licensed EAS to provide their mobile devices with a high-performance, full-featured push mobile synchronization experience now extending beyond mobile phones and into tablet devices
Trang 39WHAT IS EXCHANGE SERVER? | 7
With all of these mechanisms for retrieving and sending email, it is not unusual for users
to access their mailbox using more than one device In some cases, we have seen a single user accessing her mailbox from her desktop computer, her tablet device using Outlook Anywhere, and her Windows Phone device
In medium and large organizations, the fact that users are now accessing their mailbox from more than one device or mechanism will affect not only hardware sizing but also, potentially, your licensing costs
What’s Gone?
When Exchange Server 2007 was released, Microsoft introduced new core APIs (including Web Services, the new management API based on the NET Framework) intended to replace existing Exchange Server APIs Several of those legacy APIs were completely removed, whereas others were
deprecated—while they still worked, developers were encouraged to port their applications over
to the new APIs The deprecated APIs were not guaranteed to be continued in future versions of Exchange Server
With Exchange Server 2010, those deprecated APIs were eliminated One of the biggest was WebDAV, which was the previous HTTP-based access protocol prior to Exchange Web Services WebDAV calls are somewhat simpler to develop but are more fundamentally limited
in what they can do
How Messaging Services Are Used
Certainly, email is a key feature of any messaging system, and the Outlook Calendar is far better than previous versions of Microsoft’s appointment and meeting-scheduling software Outlook
2013 together with Exchange Server 2013 introduces even more synergy Figure 1.1 and Figure 1.2 show the Outlook 2013 client Calendar and Inbox in action
Trang 408 | CHAPTER 1 PUTTING EXCHANGE SERVER 2013 IN CONTEXT
Email clients are exciting and sexy, but to get the most out of Exchange Server 2013 you need
to throw away any preconceptions you have that messaging systems are only for email and scheduling The really exciting applications are not those that use simple email or scheduling but those that are based on the routing capabilities of messaging systems These applications bring people and computers together for improved collaboration
