Storage System brings to

Exchange 2000

! Integration with Active Directory

Exchange 2000 is a reliable, scalable messaging environment that offers a full set of features and components to support the development of collaborative solutions

Exchange 2000 is the first product to take advantage of a new data storage technology called the Web Storage System Exchange 2000 uses the Web Storage System to store all of its data An understanding of the data structure of Exchange 2000 will enable you to perceive how the Web Storage System integrates with Exchange 2000

messaging environment that

supports the development of

collaborative solutions

Versions of Exchange 2000

Exchange 2000 Server Exchange 2000

Enterprise Server

Exchange 2000 Conferencing Server

Microsoft NetMeeting

There are three versions of Exchange 2000: Exchange 2000 Server, Exchange

2000 Enterprise Server, and Exchange 2000 Conferencing Server

Exchange 2000 Server

Designed to meet the messaging and collaboration needs of businesses that need only one server running Exchange, Exchange 2000 Server is limited to a single, 16-gigabyte (GB) database per server

Exchange 2000 includes instant messaging, a function for sending an

immediate, text-based message to another user on a computer network The client software for instant messaging in Exchange 2000 is the Microsoft MSN®Messenger Service

Closely associated with instant messaging is presence information Presence

information enables one computer user to determine whether another user is currently logged on to a network, corporate LAN, or the Internet You can set presence information to indicate a particular status (for example, on the phone

or out of the office) The status is updated automatically after a period of computer inactivity

Exchange 2000 Enterprise Server

Designed for organizations that need multiple servers and features, such as unlimited message storage and the ability to have multiple stores per server, Exchange 2000 Enterprise includes instant messaging and presence

information It also includes the following features:

! Chat services Chat services provide a low-bandwidth, lightweight method of real-time communication between two or more people Chat is commonly used to build online communities of users who are interested in discussing similar topics or issues

Topic Objective

To show the environment for

each version of Exchange

2000

Lead-in

There are three versions of

Exchange 2000

! Front-end and back-end deployment Exchange 2000 can be configured as a set of front-end and back-end servers, enabling users to connect to virtual Internet Protocol (IP)–

addressable front-end servers, while storing messages and collaboration data

on separate back-end servers This configuration flexibility provides new opportunities for enterprise customers to tailor their system architecture to meet the demands of corporate acquisition and growth

! Clustering Clustering allows you to group servers that host the same set of services into manageable units to improve the reliability of the services If one server in the cluster fails, another server in the cluster can start and keep the services running Clustering support in Exchange 2000 has been enhanced to feature Active/Active clustering Based on the Microsoft Clustering Services of Microsoft Windows® 2000 Advanced Server, Active/Active clustering enables all of the servers used in a cluster to actively process messaging requests and distribute the load evenly between the servers in the cluster, thereby increasing scalability

Exchange 2000 Conferencing Server

Designed for organizations of all sizes that need to organize and manage data, voice, and video conferencing between people regardless of location You can use Exchange 2000 Conferencing Server in conjunction with Exchange Server

or Enterprise Server Exchange 2000 data conferencing allows dynamic, demand sharing of data and information by using clients such as Microsoft NetMeeting® This gives users the ability to see, chat, and share information with one another

on-Exchange 2000 Conferencing Server tracks scheduled conferences and controls attendee access to conferences For users, the benefits are single-click access to conferences and full integration into their calendars

Exchange 2000 stores its data in databases Exchange 2000 databases are more

commonly referred to as stores Exchange 2000 can store all kinds of data such

as e-mail messages, graphics, voice mail, and video presentations

Exchange 2000 supports multiple stores within one logical database All store data is kept in Joint Engine Technology (JET) databases

Store Types

There are two kinds of stores in Exchange 2000, mailbox stores and public

stores These replace the private and public information stores of earlier versions of Exchange Each store is referred to as a Web Storage System During the installation process, Exchange 2000 creates a default mailbox store and a public store

! Mailbox store A database that contains folders and items intended for use

by a single user or program A mailbox is the delivery location for all incoming messages for a designated owner Only the owner of a mailbox can access the contents

A mailbox can contain received messages, message attachments, folders, documents, and other files Information in a user's mailbox is stored in a mailbox store on an Exchange 2000 server Exchange 2000 can have multiple mailbox stores However, mailbox stores cannot be replicated to other servers running Exchange 2000

! Public store A database that contains folders and items intended for sharing

between different users and programs Public stores can contain different types of resources, ranging from custom forms to Internet content stored in its native format This database is located on the server running Exchange

2000 and can be replicated to other servers running Exchange 2000

Topic Objective

To present the default

mailbox and public stores as

displayed by the Exchange

System Manager

Lead-in

Exchange 2000 stores its

data in databases called

stores

Store Contents

Public and mailbox stores can contain the following components:

! Folders A collection of items, which can be discrete items or other folders

! Resources Any item contained in a folder, such as an e-mail message,

document, folder, HTML file, or Active Server Pages (ASP) program

! Properties Items can have any number of properties associated with them

For example, author and creation date are properties of a document

All the stores in a storage group share a common transaction log The

transaction log for a storage group contains the database transactions for all mailbox stores or public folder stores in the group Each store transaction in a storage group is written to a log file first and then to the databases When a log file reaches 5 megabytes (MB), it is renamed and a new log file is started

If a database fails, you can recover the transactions by restoring the data from the log files All of the databases in a store share the same transaction logs and usually the same backup and restore policies and procedures Keep this in mind when determining the number and placement of stores and storage groups

Exchange 2000 supports multiple storage groups You can configure up

to five stores in one storage group

Topic Objective

To depict the concept of

stores in a storage group

Lead-in

You group stores into

storage groups for easier

maintenance

Note

Folder Trees

! Public Folder Trees

! Advantages of Public Folder Trees

! Folder Tree Replicas

In each store are folder trees that contain Exchange 2000 items, such as e-mail

messages, documents, and other folders A folder tree is a hierarchy of folders

in an Exchange store Folder trees represent public and mailbox stores, each folder tree can contain multiple folders, and each folder tree represents its own store

Public Folders Tree

By default, Exchange includes a public folder tree named Public Folders The Public Folders tree provides access to the default public store and default mailbox store The Public Folders tree supports Hypertext Transfer Protocol (HTTP), Simple Mail Transfer Protocol (SMTP), Post Office Protocol 3 (POP3), Internet Message Access Protocol 4 (IMAP4), Network News Transport Protocol (NNTP) and MAPI You can create additional folder trees with the same access as the default Public Folders tree, except for support for MAPI For example, if you create a new Public Folders tree, it will not be accessible from Microsoft Outlook® 2000, which is a MAPI client

From a developer’s perspective, public folders are significant components of a Web solution Public folders provide the following advantages:

! Provide a common place for data storage and application hosting

! Configure permissions for data and applications at the folder level By doing this, if you need to move or copy an application to a different folder and adapt it for a different purpose, all of the permissions, code and data move with the application

! Are easy to adapt for a different purpose or to enhance without having to write a significant amount of code because the components are kept together This is unlike traditional applications or even other Web-based applications, which keep data, application, permissions, and other parts of the package separated

Topic Objective

To define public folder trees

and their advantages, and to

describe the features of

replicas

Lead-in

Folders provide access to

data in public stores and

mailbox stores For a

developer, public folders are

significant components of a

Web solution

Key Points

Emphasize the distinction

between a MAPI folder

hierarchy and all other folder

hierarchies In other

hierarchies MAPI can

access only the mailbox

folder and the public folder

tree, if you create a new

folder tree, everything can

access it except MAPI

Folder Tree Replicas

You can configure a folder tree to have replicas on multiple servers Replicas are useful for distributing the user load on servers, distributing public folders across geographical areas, and backing up public folder data You can set up a replication schedule based on how often data in the public folder changes You can set this schedule for all public folders or for a specific public folder You configure replication by using the Exchange System Manager

Integration with Active Directory

Benefits of Active Directory Integration

! Centralized Object Management

! Easy Access to Directory Information using LDAP

! Synchronizes Exchange Legacy Directory Information to Active Directory Using the Active Directory Connector

Previous versions of Exchange Server had a dedicated directory In Exchange 2000, all directory information (including mailboxes, information about servers, and so on) is stored in Active Directory

Active Directory stores data for a large and customizable set of objects

Integration with Active Directory provides increased system performance and manageability while making directory management easier

Some of the benefits of Active Directory are:

! Centralized object management

Unified administration of Exchange 2000 and Windows 2000 directory objects enable an administrator to manage all user data in one place, with one set of tools

! Easier access to directory information

Lightweight Directory Access Protocol (LDAP) is the preferred access protocol for directory information

! Active Directory Connector

The Active Directory Connector synchronizes directory information from a previous Exchange System directory to Windows 2000 Active Directory

Topic Objective

To list the benefits of

integrating Active Directory

# Introduction to the Web Storage System

! Web Storage System Overview

! Web Storage System Database Features

As stated previously, Exchange 2000 is the first product to incorporate Web Storage System technology

Web Storage System combines the features and functionality of the file system, the Web, and a collaboration server through a single location You can use the Web Storage System for storing, accessing, and managing Exchange data, as well as for building and running programs In the future, other Microsoft products will also include the Web Storage System

file://.backofficestorage/nwtraders.msft/public folders/Survey/SuzanFine.xls http://servername/public/Survey/SuzanFine.xls

Although you store items in Exchange 2000 databases, you use the Web Storage System technology to access the items The Web Storage System is a database organized into a hierarchy of folders

Web Storage System Resources

Each folder in the Web Storage System can contain any number of items, called

resources A resource can be any Exchange item, such as an e-mail message, an

appointment, contact information, streaming video, or another folder

Every resource in the Web Storage System has a URL that you can use to access the resource For example, a survey document in a public folder may have the following URL:

http://servername/public/Survey/PaulWest.doc Another example is a contact in an administrator's Inbox with the following URL:

Web Storage System Schema

The Web Storage System provides a default schema A schema is a collection

of properties that are associated with a resource With the Web Storage System schema you can perform tasks such as describing resources, implementing security on resources and folders, and providing business logic

The default schema provides a set of properties that satisfy the requirements of most solutions For example, the Web Storage System recognizes e-mail messages stored in Exchange 2000 as a type of resource (message) and

associates the To, From, and Subject properties with the resource You can use

schema properties to index, sort, and query resources just as you would on a relational database, such as Microsoft SQL Server™ For example, you can perform a search on all expense report resources that have the custom property total set to a value of over $500.00

You can also extend the default schema for use in your programs For example, you can create the schema definition for an expense report and associate default schema properties of the Web Storage System and custom properties with the definition

Web Storage System Database Features

! Multiple Database Support

! Native File Format Support

! Streaming Media Support

! Content Indexing and Searching Support

Each store in Exchange 2000 is a Web Storage System database The Web Storage System database offers flexibility for developing programs

Multiple Database Support

You can define multiple stores with Exchange 2000 Because stores have no size limit, you can use multiple stores placed on different servers to enhance the flexibility of backup and restore tasks, indexing, and replication In addition, you can configure nearly every store control on a store-by-store basis

Smaller physical stores increase overall system reliability, enable a much faster backup process, and speed up the recovery process in the event of hardware failure For example, if the hardware that contains one of your stores fails, only that store is affected during repair, while any stores contained on different hardware continue to serve their e-mail users

Native File Format Support

Web Storage System supports the storage of multimedia formats and Multipurpose Internet Mail Extensions (MIME) content Client applications or any computer operating environment that uses standard Internet protocols such

as HTTP, SMTP, IMAP4, and POP3 can store audio, video, voice, or other multimedia formats as streams of MIME data in the Web Storage System without conversion into another format, which was required by earlier versions

of Exchange

Streaming Media Support

By using the file streaming interfaces of the Web Storage System, you can store resources, such as multimedia files, in their native format to ensure data

integrity You can access these resources while they are streaming to the client instead of waiting for the entire file to download

Topic Objective

To list the database features

of the Web Storage System

Lead-in

Each Exchange store is a

Web Storage System and

uses the Web Storage

System to access items in

the store

Note

Content Indexing and Searching Support

The Web Storage System optimizes search capability by supporting indexes for

common schema properties, such as message Subject, Body, From, To, and

Email Address The Web Storage System supports Structured Query Language

(SQL) syntax and content indexing, which provides full-text search function (including attachments) and means that MAPI text searches are extremely fast

! Content indexing A feature that provides a fast-search capability Because

this capability is built-in, no additional software is required and searches made by earlier versions of applications are enhanced The searches performed by current versions of applications, such as Outlook Web Access forms and Outlook 2000, do not require you to write new code

! Search folders Folders in the Web Storage System that contain the results

of previous searches that can be accessed after the initial search when you later perform more efficient searches For example, if a search is performed for all Word documents, by a specific author, in the Web Storage System, the search results can be stored in a new search folder and accessed when the user wants to perform another search, such as one to access all Word documents of the same author that where created before a specified date

# Developmental Features of the Web Storage System

! Internet Technologies Support

! Outlook Web Access Support

! Supported Microsoft APIs

! Web Form Support

! CDO for Exchange 2000

! Event Support

! Workflow Support

The Web Storage System is a great foundation for building applications in Exchange 2000 The Web Storage System supports a wide range of protocols and has a rich set of development features for creating solutions

Topic Objective

To list the topics related to

Web Storage System

Application Development

Lead-in

The Web Storage System

provides developers with a

wide range of supported

features and tools to build

applications

Internet Technologies Support

! HTTP Enables URL Accessibility

! WebDAV Provides Greater Flexibility When Working with Resources

! XML Enables Sharing of Data Between Applications and Across Computer Platforms

! ASP Pages Perform Programming Logic on the Server

! Internet Mail Protocols such as SMTP, NNTP, and POP3

The Web Storage System and Exchange 2000 are tightly integrated with Internet Information Services (IIS) to provide a wide range of features that enable access to Exchange 2000 data by using Internet standards and protocols Users can access resources, lock and unlock files, configure security, or check e-mail messages by using Internet standards protocols

You can access resources with the Web Storage System by using the following protocols:

! Web Distributed Authoring and Versioning (WebDAV)

You can access resources in the Web Storage System by using WebDAV, which is an extension of HTTP WebDAV has greater flexibility when working with resources in the Web Storage System, especially during

collaboration among developers For example, you can put a LOCK

(WebDAV method) on a file that you are modifying that prohibits other

team members from modifying the file until the LOCK is released

Use WebDAV to access the properties associated with resources in the Web Storage System You can search for and set the values of properties on a

resource by using the SEARCH and PROPPATCH WebDAV methods

The Web Storage System

supports a wide range of

Internet technologies for

building Web-based

applications

! Extensible Markup Language

Extensible Markup Language (XML) is the universal language for data on the Web XML is similar to HTML in that it uses tags such as

<H1>Heading</H1> to describe content XML defines the properties of the data and HTML describes how to display data XML is a tool for reusing and sharing data from application to application and from computer to computer regardless of the operating environment

WebDAV uses HTTP to send client requests, such a LOCK request, as

XML text Exchange 2000 and Web browsers, such as Microsoft Internet Explorer 5, are capable of interpreting XML text as data and present the data accordingly

! Active Server Pages

The Web Storage System supports Active Server Pages (ASP) pages and has the ability to process ASP scripts when accessed by clients by using HTTP You can build Internet applications with Exchange 2000 and the Web Storage System just as you do with IIS You can still use Microsoft Visual Studio® or Microsoft FrontPage® 2000 to create these applications

! Supported Internet mail protocols

Users can access e-mail messages stored on Exchange 2000 by using standardized Internet protocols such as SMTP, POP3, and IMAP4

Client applications that support these protocols enable users to access the Inbox Users can also participate in Internet newsgroup discussions by using Network News Transfer Protocol (NNTP), which allows users to post messages and documents to share with other users

Outlook Web Access Support

Microsoft Outlook Web Access for Exchange 2000 provides a secure environment that enables users to access Exchange 2000 data by using a Web browser, such as Microsoft Internet Explorer From a UNIX, Macintosh®, or a computer running Microsoft Windows connected to the server, a user with the correct permissions can view and work with any public folder, global address list (GAL) as well as their Inbox and calendar

Outlook Web Access is capable of responding to Web browser characteristics when rendering a response to a client computer For less advanced browsers, Outlook Web Access is capable of generating an HTML view that can be displayed by any HTML 3.2-compliant Web browser Outlook Web Access is also capable of generating more robust views for advanced clients, such as Internet Explorer 5, which use Dynamic HTML (DHTML) and XML

Consider the following:

! When a user sorts or queries an Outlook Web Access view by using an HTML 3.2–compliant browser, the server must process the request and send the HTML file back to the client computer for viewing The Web browser cannot interpret data locally so the server processes the request and sends the HTML 3.2 view to the client computer, which places an extra load on server resources and also results in longer waiting periods for users

! If a user requests data in an Outlook Web Access view by using an HTML 4.0-compliant browser, the data is sent in XML format to the client computer If the user sorts or queries the data, the operation is performed locally on the client; thereby increasing the process time experienced by the user—without affecting network performance

Topic Objective

To show the Outlook Web

Access user interface

Lead-in

Outlook Web Access

enables a user to access
