The service threw an unexpected exception which was caught at %1(%2)

Explanation

This alert event indicates that the Address List Service cannot stamp Exchange attributes on Active Directory objects. When this event is being logged, users may not appear in the global address list (GAL). Additionally, users may not be able to access their Exchange mailboxes. These GAL display problems and mailbox access problems may occur if an internal class incorrectly processes certain threads that run at the same time.

User Action

To resolve this event, do one or more of the following:

  • Review the Application log for related events. For example, events that occur immediately before and after this event may provide more information about the root cause of this error.

  • Examine the server for a dump file produced by Dr. Watson, the Windows Server default debugger.

If you are having difficulty resolving the issue, contact Microsoft Product Support. For information about contacting support, visit the Contact Us page of the Microsoft Help and Support Web site.
