This topic explains how to configure Microsoft Exchange services, such as the Availability service, for the Autodiscover service on a Microsoft Exchange Server 2007 computer that has the Client Access server role installed.

When you enable Outlook Anywhere, you must also configure external access to Microsoft Exchange services for the Autodiscover service. This includes the URLs for the Availability service, Exchange Web Services, Unified Messaging (UM), and the offline address book.

If you do not configure the external URL values, the Autodiscover service information provided to the Microsoft Office Outlook 2007 client may be incorrect for clients that are connecting from outside your network. They may be able to connect to their Microsoft Exchange mailbox. However, they will be unable to use Exchange features such as Out of Office functionality, the Availability service, Unified Messaging, or offline address book downloads.

Generally, the internal URL is configured by Microsoft Exchange Setup. However, the external URLs must be configured by using the virtual directory cmdlet for each component.

Before You Begin

To perform the following procedures, the account you use must be delegated the Exchange Server Administrator role and membership in the local Administrators group for the target server.

For more information about permissions, delegating roles, and the rights that are required to administer Exchange 2007, see Permission Considerations.
