Because the /owa virtual directory (vdir) is the only vdir used when accessing a user mailbox stored on an Exchange 2007 Mailbox Server, this is also the vdir under which you confi gure most of the OWA-related functionally (I say most since some settings must still be confi gured using the IIS Manager)

Let’s take a closer look at the confi guration options available on the Property page of the owa virtual directory

The fi rst tab, which is the General tab shown in Figure 5.18, shows us information such as the name of the CAS, the Web site to which the owa vdir belongs, as well as the Exchange version and the last time the vdir was modifi ed In addition, this is where we can specify the Internal and External URL used to access OWA (the internal URL will always be pre-entered)

NOTE

With Exchange Server 2007, you can longer access Public Folders using the

OWA 2007 interface

Table 5.2 Continued

Virtual Directory Version Description

Public Exchange 2000, 2003 This virtual directory is used to

access public folders by using the Outlook Web Access application for mailboxes located on computers running Exchange 2007, Exchange Server 2003, or Exchange 2000 Server Only public folders on servers that are running Exchange 2003 or Exchange 2000 will be available through Outlook Web Access

Moving on to the Authentication tab (Figure 5.19), here we have the option of specifying the

authentication method used to authenticate OWA users Notice forms-based authentication is

enabled by default, unlike OWA 2003 where you had to enable this feature manually If for some

reason you don’t want to have forms-based authentication enabled, you can choose to switch to basic

by clicking Use one or more standard authentication methods One reason you might want to

do this is because you have an ISA Server 2006 deployed in your perimeter network and you are

using it to pre-authenticate user logons, thus enabling Basic authentication instead.

Before we move on, I want to bring your attention to the sentence in the bottom on the Authentication window pane, which says that in order to confi gure SSL settings for the Outlook Web Access virtual directory, you should use the IIS Manager Since the SSL certifi cate that is installed on the Default Web Site is a self-signed untrusted SSL certifi cate, there will come a day where you want to replace it with an SSL certifi cate from a third-party certifi cate provider (I showed you how this was done in the previous section in this chapter)

Now click the Segmentation tab shown in Figure 5.20 In previous versions of Exchange,

segmentation was very complex to confi gure, because you had to do so directly in the Registry (at least until the Exchange 2003 Outlook Web Administration tool was released) With Exchange Server 2007 it couldn’t be easier You simply select the feature you want to disable, click the

Figure 5.19 The Authentication Tab on the OWA Property Page

Disable button and that’s it You don’t even have to do an IISRESET /noforce afterwards

Most impressively, there is no need to log off and back on since the change is applied immediately!

TIP

If you want to turn off an OWA feature for one or more users, you can do so using

the Set-CASMailbox cmdlet For example, we can turn off the calendar for a user

with the following command:

Set-CASMailbox <user> -OWACalendarEnabled: $False

The next tab is the Public Computer File Access tab, shown in Figure 5.21 Here we can enable and disable direct fi le access Direct fi le access is a feature that makes it possible for your users to open any fi le that is available through OWA This is not only fi le attachments, but also

fi les located in Windows SharePoint Services document libraries and/or on Windows fi le server shares
