Transport Service in Exchange 2010 will not start - Poison Queue
Posted on 2012-03-21
After a SBS 2003 to 2011 migration, the Transport service starts and stops. The event logs refer to the Poison Queue having more than 2 messages. However in the services console the Transport service shows started, but when I open up the Queue Viewer in ESM, to deleted the messages in the Poison Queue, the queues do not load and a message pops up saying the Transport service is not running.
When I restart the services in the service console and refresh constantly the queue viewer, I see the four queues including the Poison queue that has 210 messages, then they go as the transport services stops.
As a result of this, port 25 is closed and no mail flow occurs.
Can anyone help?
