| Description | The processing of Pickup file %1 caused the transport process to fail. Pickup file %1 will be renamed. |
| Event Information | According to Microsoft : Cause : 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 2007 system after a server failure. The poison message queue is typically empty. If no poison messages exist, the poison message queue does not appear in the Queue Viewer or the output of the Get-Queuecmdlet in the Exchange Management Shell. You can delete the messages if they are harmful to the system. If the event that caused the message to enter the poison message queue is unrelated to the message, you can resume delivery of the message. Resolution : To resolve this warning, do one or more of the following: 1.Take no action, except send the poison message file that caused the failure of the Microsoft Exchange Transport service to Microsoft Customer support for analysis. 2.If you are confident that specified message file had nothing to do with the failure of the Microsoft Exchange Transport service, you may resubmit the poison message file. |
