Yossi, a BizTalk Server Administrator at HWLC Motors, has been asked to shut down the Part Recall BizTalk application at 12 a.m. He is not supposed to allow any new Part Recall requests into the system after 12 am but needs to ensure that any messages from the previous day are completed before completely turning off the application. Upon launching the BizTalk Administration Console, he discovers that there are five messages that are currently being processed that were received at 11:59 p.m. from the previous day. What should Yossi do to prevent losing these five messages while not allowing any new messages into the system?
