Hi guys! I need your help. I need to check how many CALS were installed in my Exchange Server 2007. Is there a way to check this?

The only real way to know is to contact your licensing rep. Exch doesnt track that.

Oh ok and that is where we bought the licenses, right?

Yes, I would contact whomoever you bought the licenses from if you cant determine how many you have. you can contact Microsoft as well for volume licensing issues: https://www.microsoft.com/licensing/servicecenter/Registration.aspx

Agree with andy.Per my known, there is good software help you manage the asset including the lisence. You could refer to below:http://www.microsoft.com/sam/en/us/default.aspxRegards!gavin
