Exceptions
Remarks
The UseJournalQueue and UseDeadLetterQueue properties specify how Message Queuing tracks a message. If UseDeadLetterQueue is true, delivery failure (of a non-transactional message), causes the message to be sent to the non-transactional dead-letter queue on the computer that could not deliver the message. (Deliver failure could be caused by a message timer expiring, for example.)
In the case of delivery failure for a transactional message, Message Queuing sends the message to the transactional dead-letter queue on the source machine in all negative and in-doubt cases.
When you store messages in a dead-letter queue, you should clear the queue periodically to remove messages that are no longer needed. Messages stored in dead-letter queues count against the size quota for the computer where the queue resides. The computer quota is set by the administrator and refers to the size allocated for storing messages on the whole computer, not just in a single queue.
Note You do not create a journal or dead-letter queue. These are both system queues that Message Queuing generates.
