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 Access 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 Access. 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 Server 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 Server virtual directory configuration data from Active Directory.
The Client Access server that accepts Outlook Web Access proxy or redirection requests is not in the same Active Directory site as the computer that is running the Mailbox server role.
For more information about Outlook Web Access proxying and redirection, see Understanding Proxying and Redirection.
