A. The Exchange Server Internet Mail Service (IMS) has its own Queues tab, so you can see how many items are parked in each queue. The X.400 connector, alas, doesn’t have a Queues tab. However, you can take an alternate route to see the number of messages in the X.400 connector queue: Open the Message Transfer Agent (MTA) Properties dialog box, select the Queues tab, and select the X.400 connection from the Queue Name list box.
