Public Store: Messages Queued for Submission - sustained for 15 minutes - Yellow(>25).


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

This alert indicates that the number of replication messages in the public store that are queued for submission to a transport server has been greater than 25 for 15 minutes. This alert may be caused by problems with the Microsoft Exchange Mail Submission Service on the Mailbox server, higher than normal load on the transport server, or a resource bottleneck on the transport server.

User Action

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

  • Verify that the Mail Submission Service is running on the Mailbox server.

  • Determine if there is a bottleneck, and if so, which resources are creating the bottleneck. If a bottleneck exists, attempt to mitigate the problem. Possible bottlenecks include disk reads or writes, processor time, available memory, and network configuration.

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.

If you are not already doing so, consider running the tools that Microsoft Exchange offers to help administrators analyze and troubleshoot their Exchange environment. These tools can help you make sure that your configuration is in line with Microsoft best practices. They can also help you identify and resolve performance issues, improve mail flow, and better manage disaster recovery scenarios. Go to the Toolbox node of the Exchange Management Console to run these tools now. For more information about these tools, see Toolbox in the Exchange Server 2007 Help.
