Explanation

This Warning event indicates that Microsoft Exchange ActiveSync tried to access a mailbox on a computer that has the Mailbox server role installed, but detected that the Mailbox server cannot handle requests. This may be caused by the following conditions:

• A Microsoft Exchange database is dismounted.

• The Mailbox server is offline for maintenance.

User Action

To resolve this event, consider the following:

• If this event is logged infrequently, or only during scheduled downtime for a Mailbox server, no user action is required.

• If this event is frequently logged, do one or more of the following:

  • Make sure that the databases on the Mailbox server are mounted.

  • Review the Application log on the Mailbox server to determine the root cause of the Mailbox server being offline.
