@TomF I’m experimenting right now with approach I suggested above (using TransactedSession). My test solution consists of a queue producer and queue consumer. Producer sends 5 messages to the queue. Consumer accepts first 2 (by calling transactedSession.Commit()) then only 3rd one is being rejected (by calling transactedSession.Rollback()). I setup dead message queue and set Maximum Redelivery Count to 3. As a result for some reason I got 3 messages in the DMQ (3,4 and 5) but I expected only message 3 go there. Am I missing something here?
