Cool tip. If you are running Lync 2010, and want to see the current Configuration Information. In the systray, the icon, hold CTRL and right click, and you will get a configuration information menu. Click that and you get your info
From here you can see your URL’s and if everything is set up the way you want it to be. One thing to note, the “refresh” button doesn’t seem to do anything. You need to close the window and reopen it to see changes.
(As a note, you can do the same with with Outlook, and get to the testing menu to test connectivity and configuration)
