Cross-forest lookups fail in Exchange Server 2007 SP3 Update Rollup 6

Symptoms

Cross-forest free/busy information lookups fail in Microsoft Exchange Server 2007 Service Pack 3 (SP3) Update Rollup 6. However, free/busy information lookups for users in the same forest work as expected.

Cause

This issue occurs if Outlook Anywhere is not enabled in the target forest.

Workaround

To work around this issue, enable Outlook Anywhere in the target forest, and then verify that the external URL for Exchange Server Web Services is configured correctly. To do this, follow these steps.

Note The client access servers in the source forest must be able to connect to the external URL for Exchange Web Services.
  1. Enable Outlook Anywhere in the target forest. For information about how to enable Outlook Anywhere, visit the follow TechNet website:
  2. Configure the external URL for Exchange Web Services for the target forest. To do this, run the following command in Windows PowerShell for Exchange:

    Set-WebServicesVirtualDirectory -identity “server_name\EWS (Default Web Site)” -ExternalURL https://mail.contoso.com/ews/Exchange.asmx

    Note In this command, contoso is a placeholder for the appropriate domain name.

More Information

Exchange Server 2007 SP3 Update Rollup 6 uses the external URL for Exchange Web Services to connect to the target forest. Because the external URL for Exchange Web Services cannot be returned by the AutoDiscover service if Outlook Anywhere is not enabled in the target forest, the cross-forest lookup fails.
