Mail Submission Service is experiencing issues: Messages Queued For Submission - sustained for 15 minutes - Red (>25).

Explanation

The Messages Queued for Submission performance counter indicates the number of messages in the mailbox store that are ready to be sent and that are waiting to be submitted to a transport server.

This alert indicates that that the number of messages in the mailbox store that are queued for submission to a transport server has been greater than 25 for 15 minutes. This alert may be caused by any of the following conditions:

  • Problems that affect the Microsoft Exchange Mail Submission service on the Mailbox server

  • A higher than normal load on the transport server

  • A resource bottleneck on the transport server

User Action

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

  • Verify that the Microsoft Exchange Mail Submission service is running on the Mailbox server.

  • Determine whether a bottleneck exists and, if so, which resources are creating the bottleneck. After you find the cause of the bottleneck, try to mitigate the problem. Possible bottlenecks include disk reads or writes, processor time, available memory, and network configuration.
