The PROPID_M_DEST_QUEUE property identifies the target queue of the message.
The PROPID_M_DEST_QUEUE property is only used by the receiving application. MSMQ attaches this property to the message according to the destination queue specified in the call to MQSendMessage.
When PROPID_M_DEST_QUEUE is passed to MQReceiveMessage, PROPID_M_DEST_QUEUE_LEN must be passed as well.
PROPID_M_DEST_QUEUE is typically used when the receiving application wants to determine the destination queue of a message in a journal or dead letter queue. For information on journal and dead letter queues, see Journal Queues and Dead Letter Queues.
