This Warning event indicates that the processing of the specified message file in the Pickup directory or the Replay directory caused the Microsoft Exchange Transport service to fail.

Any message that causes the Microsoft Exchange Transport service to fail during message processing is classified as a poison message. Poison messages are put in the poison message queue. The poison message queue is a special queue that is used to isolate messages that are detected to be potentially harmful to the Microsoft Exchange Server 2010 system after a server failure. For more information, see Understanding Transport Queues.

  • If you are confident that the specified message file had nothing to do with the failure of the Microsoft Exchange Transport service, you may resubmit the poison message file. For more information, see Resubmit Messages in Queues.
