In Microsoft BizTalk Server 2010, BizTalk Server 2013 R2, or BizTalk Server 2013, you use the MQSeries adapter to receive and process a large volume of messages. However, you notice that the messages are not kept in the correct order, even though the Order Delivery option is enabled in the receive location.
