How is CAL licensing handled? We would like to track out Exchange CAL licensing. I have created a license and selected the CAL license type using the per mailbox option. How do we attach the CAL to a mailbox in the Exchange server? We would like to track the number of CAL's versus the number of mailboxes existing on the Excahnge server to insure we are within licensing compliance.

 

We also would like to track CAL licensing for SQL server, Windows server, Lync Server, and SharePoint.
