MSMQ messages received but not delivered Windows 2008 R2

Question

I have a transactional queue called myPrivateTransactionalQueue hosted on a Win2008R2 server called myReceivingServer which should receive messages from another server calle

Answer 1

Check the sender dead letter queue for a clue.

On my case, after checking the sender dead letter queue I was able to identify that it was a permissions issue.

When the queue is unauthenticated it is not enough to give permissions to "everyone" but "anonymouns logon" must also be there with at least send permissions.
