Although a number of items were left out of Exchange 2007 RTM’s GUI interface, the Queue Viewer wasn't one of them. The Queue Viewer is a useful utility that gives you an at-a-glance way to look for messages on your server that might be clogged up. The viewer is found by opening up the Exchange Management Console and clicking the Toolbox option at the left side of the screen. See Figure A for a look at the Queue Viewer main window.
Figure A shows the active communication with other SMTP servers as well as a list of domains to which mail may not be flowing for some reason. You’re also provided with a reason that communications may be failing with a particular domain. Note also that you’re shown the number of messages sitting in a particular queue. If you double-click a particular queue, the Queue Viewer will show you a list of messages waiting in that queue.
Figure B Note that there is a message in the yaho.com queue in Figure B. It’s likely that this message is still sitting as the user probably intended to type yahoo.com instead of yaho.com. Select a message in the list and other message details, including the subject, show up in the Actions pane.
If you want more details about the message, click the Properties option in the Actions pane. The Properties page for a message gives you a lot of information about the message, including the sender, recipient, the message size, the last error associated with the message and much more.
Figure C If a particular message, such as the one shown in Figure C, is never going to be received because of a typo or some other error, you can forcibly remove it from the queue. From the Actions pane shown in Figure B, click the Remove (with NDR) action to let the sender know that the message failed to be delivered. If you don’t want the sender to know that message delivery was interrupted, choose the Remove (without sending NDR) option instead.
