Summary

The message could not be moved to deadletter queue. Deadletter queues should not require privacy of messages. The message will be moved to the system transactional dead letter queue.

Causes

This problem could be because:

The privacy level of the specified dead-letter queue might be other than None or Optional or the messages that are being sent to the queue are not encrypted.

Resolutions

Change encryption levels

To allow messages to enter a dead-letter queue, set the privacy level of the specified dead-letter queue to None or Optional, or ensure that the messages that are being sent to the queue are encrypted.

For more information about changing the privacy level of queues, see Change the Privacy Level for Queues ( http://go.microsoft.com/fwlink/?LinkId=104733).

For more information about sending encrypted messages, see Message Queuing-Encrypted Messages ( http://go.microsoft.com/fwlink/?LinkId=104734).
