Message Text

Outlook Web App isn't available for this mailbox. The Client Access server %1, running Exchange version %2, tried to find a Client Access server to proxy Outlook Web App traffic for mailbox %3. It couldn't find the Client Access server in the target Active Directory site.%n%nAdditional information: %4. If the problem continues, contact your helpdesk.

Explanation

This Warning event indicates that the computer that is running the Client Access (CAS) server role could not determine the Client Access server that should handle a Microsoft Office Outlook Web App request. Specifically, it could not determine whether the request should be processed by the local Client Access server, or if it should be proxied or redirected to a Client Access server in a different Active Directory site. Therefore, the mailbox specified in the event description could not be accessed through Outlook Web App. This event may be caused by one or more of the following:

  • The Client Access server cannot verify the location of servers that are running Microsoft Exchange in Active Directory sites.

  • The Client Access server cannot verify the links between the Active Directory sites.

  • The Client Access server cannot access required Exchange virtual directory configuration data from Active Directory.

  • The Client Access server that accepts Outlook Web App proxy or redirection requests is not in the same Active Directory site as the computer that is running the Mailbox server role.

User Action

To resolve this error, take one or more of these steps:

  • If this occurs frequently, check network connectivity between the Client Access Server and domain controllers. Use the Ping or PathPing command-line tools to test basic connectivity. Use Ping to isolate network hardware problems and incompatible configurations. Use PathPing to detect packet loss over multiple-hop trips. For more information, see Microsoft Knowledge Base article 325487, How to troubleshoot network connectivity problems.

  • Make sure that the InternalUrl of the Outlook Web App virtual directory exists and that it matches the fully qualified domain name (FQDN) of the local CAS server.
