The Microsoft Exchange RPC Client Access service crashes intermittently on a Microsoft Exchange Server 2010 server. Additionally, the following event is logged:
- This issue typically occurs when a delegate of a mailbox accesses the mailbox, mailbox audit logging is enabled and the Microsoft Exchange Active Directory Topology service is stopped on the server.
- When this issue occurs, clients cannot connect to the Exchange Server 2010 server.
This issue occurs because a System.InvalidOperationException exception occurs.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
