This topic provides an overview of administration for Microsoft Office Outlook Web Access in Microsoft Exchange Server 2007. Exchange 2007 Outlook Web Access offers significant improvements over earlier versions. These include new features for administering Outlook Web Access and a user interface that offers richer functionality and is easier to use. For more information about the improvements in Outlook Web Access, see Client Features in Outlook Web Access.

New features, such as segmentation and explicit logon, are available only when you use an Exchange 2007 computer that is running the Client Access server role to connect to an Exchange 2007 server that is running the Mailbox server role.

Tools for Managing Outlook Web Access

Table 1 lists the tools that you can use to configure and manage Outlook Web Access in Exchange 2007.

Table 1   Tools for managing Outlook Web Access

Tool Description

Exchange Management Console

This graphical user interface is used to manage an Exchange 2007 organization. The Exchange Management Console can be used to manage the most common settings for Outlook Web Access.

Exchange Management Shell

This command-line interface for Exchange Server and the associated command-line plug-ins automate administrative tasks and management for many features that are not included in the Exchange Management Console.

Internet Information Services (IIS) Manager

IIS Manager is used to manage user access to the Outlook Web Access virtual directories, for example, simplifying the URL and forcing users to use an HTTPS address.


Some Outlook Web Access settings, such as the ConnectionCacheSize and MaxRequestLength values, must be configured by modifying Web.config because these settings are specific to ASP.NET. Web.config should be modified only by using tools such as Notepad. If you modify web.config by using IIS, you will corrupt the file.

Registry Editor

Some Outlook Web Access configuration settings, such as the PublicClientTimeout, TrustedClientTimeout, and SSLOffloaded values must be configured by using Registry Editor.

   Incorrectly editing the registry can cause serious problems that may require you to reinstall your operating system. Problems resulting from editing the registry incorrectly may not be able to be resolved. Before editing the registry, back up any valuable data.

Administrative Tasks for Managing Outlook Web Access
