Lync Server call detail recording (CDR) agent failed to process messages in the CDR dead letter queue.

Error Code: %1!_HRX!
Cause: This can occur if the archiving agent cannot read message from the dead letter queue or cannot resend messages to the call detail recording (CDR) queue.
Resolution:
Verify that Lync Server archiving agent has the appropriate permissions to read messages from the CDR dead letter queue and that Message Queuing has enough resources to process messages.
