Hi, "Exists" will not work with the deadletter queue. This is a system queue that always exists. Just try using it. BTW it will probably work only on the machine with the specified QM GUID (c382cb83-73a5-c2b9-00a0-216fa6a87965), and not with remote machine, because Windows CE does not fully support Active Directory integration. If want to write a code that will work from any machine, either

The following works fine under ActiveDomain MSMQ: m_qDeadLetter = new MessageQueue(".\\DeadLetter$"); But under Workgroup throws the following error: A workgroup installation computer does not support the operation. at System.Messaging.MessageQueue.GetMachineId I also tried: .\System$\Deadletter$ .\System$\Deadletter DIRECT=OS:.\Deadletter$ DIRECT=OS:.\SYSTEM$;DEADLETTER But no

Thanks Yoel, It appears to be working okay now that I better understand the time to reach queue versus time to be received relationship. I have set the time to reach queue to a nominal value of 15 minutes and set the time to be received to 45 minutes. That may be more than necessary but testing shows the transactions are completing successfully now and no messages are showing up in the
