Poison Queue Length - sustained for 5 minutes - Red(>5) - Edge Transport.

The Poison Queue Length performance counter measures the number of messages currently in the poison queue. Messages in the poison message queue are in a permanently suspended state.

This alert indicates that the Poison Queue Length has been greater than 5 for five minutes.

The poison message queue contains messages that are determined to be potentially harmful to the Microsoft Exchange Server 2010 server after a server failure. The messages may be genuinely harmful in their content and format. They may also be the results of a poorly written agent that has caused the Exchange server to fail when it processed the supposedly bad messages.

Messages remain in the poison message queue until they are manually resumed or removed by an administrator. The messages in the poison message queue are never automatically resumed or expired.

To resolve this alert, resubmit or remove the messages from the poison message queue. You can resubmit the messages by using Exchange Queue Viewer or by running the Resume-Message cmdlet. You can remove messages by using Queue Viewer or by running the Remove-Message cmdlet. 

Note   You cannot resubmit messages in the poison queue using the Retry-Queue cmdlet with the Resubmit parameter.

For detailed steps about resubmitting messages in the poison queue, see the "Resubmit messages located in the poison message queue" section in Resubmit Messages in Queues.

For detailed steps about removing messages from the poison queue, see Remove Messages from Queues.

If you are not already doing so, consider running the Exchange tools, which have been created to help you analyze and troubleshoot your Exchange environment. These tools can help make sure that your configuration aligns with Microsoft best practices. They can also help you identify and resolve performance issues and improve mail flow. To run these tools, go to the Toolbox node of the Exchange Management Console. To learn more about these tools, see Managing Tools in the Toolbox.
