Remarks

ExactlyOnce, when set to true, indicates that Message Queuing (also known as MSMQ) ensures that a sent message is delivered to the receiving message queue once and only once. If delivery fails, the message is sent to the dead-letter queue depending on the DeadLetterQueue property setting. Setting ExactlyOnce to true requires the queue to be transactional.
