How to known CAL is working or not in windows server 2012 ?

Hi,

Lync CAL's (as well as the Lync Server license) operate on an honour system. You do not input or activate CAL's in a Lync environment, as such they cannot be deemed 'working' or 'not working'. Simply ensure you have enough CAL's to cover your user requirements in the event you are audited.

Kind regards

Hi Amol Kr,

To access Lync Server 2013 as an Active Directory (AD) authenticated user, a CAL is required. A CAL is a license that gives a user the right to access the services of the server.

If you have any question with Lync Server CALs, I suggest you Contact Microsoft Customer Support Services to get help. For a complete list of Microsoft Customer Support Services telephone numbers and information about support costs, visit the following Microsoft website:

You can use this script to report the required CAL's for Lync and Exchange:
