Messages never arrive in the queue

Question

I use NServiceBus with MSMQ on Windows Server 2008. In one of our scenario we send a command to another server queue but sometimes the message never arrives in the queue and MSQM doesn't throw an exception.

I have written a small application that sends a message directly to the queue without NServiceBus and I have encountered the same problem.

I think it isn't a nservicebus problem but a MSMQ problem : windows security, network,...

How can I force MSMQ to return an error when the message can't be saved in queue ? What are the possible reasons of this behavior ? Where are the messages that have disappeared ?

Answer 1

In the MSMQ Management snap-in take a look at the system queues and look at transactional dead letter and non-transactional dead letter queues. Also be sure to have setup queue ACL correctly.
