Active Sync is temporarily suspending requests to an unresponsive mailbox server. Users with mailboxes on this server may not be able to sync until the server recovers. |
Explanation
This Error event indicates that Microsoft Exchange ActiveSync tried to access a mailbox on a computer that has the Mailbox server role installed but, instead, detected that the Mailbox server cannot handle requests. This problem 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 problem, consider the following situations:
If this event is logged infrequently or is logged only during scheduled downtime for a Mailbox server, no user action is required.
If this event is logged frequently, 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 offline status of the Mailbox server.
