Alert Type

Error

Rule Path

Rule Name

The OnSubmittedMessage agent did not handle a catchable exception.

Explanation

This Error event indicates that the transport agent specified in the event description threw an unhandled exception when it tried to process a message. The first time that a message triggers this exception, the Microsoft Exchange Transport service will crash. If the message is processed again and causes the same unhandled exception, the message is moved to the poison message queue. 

The poison message queue is a persistent queue that isolates messages that are detected as potentially fatal to a computer that is running Microsoft Exchange Server 2010. This queue is typically empty. If no such messages exist in the poison message queue, the queue does not appear in the queue viewing interfaces.

User Action

To resolve this error, follow these steps:

  • Review the event description to identify the transport agent that triggered the unhandled exception.

  • If the transport agent is written by Microsoft, contact Microsoft Product Support Services. For more information about how to contact support, visit the Microsoft Help and Support Web site.

  • If the transport agent is not written by Microsoft, contact the software vendor who provided the transport agent.

  • If the message was transferred to the poison message queue, we recommend that you contact Microsoft Product Support to report the potentially harmful message that Exchange detected. For more information about how to contact support, visit the Microsoft Help and Support Web site.

Note   Do not delete the poison message from the Poison Message queue. Microsoft Product Support Services may have to examine the message.
