Explanation

This Error event indicates that the Microsoft Exchange Availability service did not logon as a network service. The Exchange Availability service retrieves the Schedule+ Free Busy and Out-Of-Office (OOF) data for a set of mailboxes residing on a computer that is running Exchange Server 2007 or Exchange Server 2010. When the Exchange Availability service cannot directly connect to a mailbox that resides in a remote Active Directory forest, it sends a proxy Web request to another instance of the Exchange Availability service that is running in the remote Active Directory forest by using Kerberos authentication. If Kerberos authentication fails, Network LAN Manager (NTLM) authentication is used. Under NTLM authentication, the Web request for a cross-site or cross-forest Exchange Availability service that is running under the context of a local computer uses an Anonymous user account.

The cross-site or cross-forest Availability service cannot authenticate an incoming Web request that uses an Anonymous user account. Therefore, the cross-site or cross-forest Availability service must impersonate the network service context. This means that even under NTLM authentication, the Web request for cross-site or cross-forest Exchange Availability service uses a local computer account. This event is logged when the Exchange Availability service does not create the network service authentication context.
