I am about to implement a deticated Exchange 2013 enterprise server, with windows 2012 server its going to be a central server for 250 users, this means the server is on a central location and users are connecting remotely to this server. The clients will only be accessing trough outlook , i understand i need 250 Exchange 2013 User CAL's, but do i also need need Windows Server 2012 CAL's ? thanks in advance !

Hi, When you implement Windows Server 2012 at the first server you will need to update the license for all users that will use this server, even for Exchange 2013. Eli. Unified Communication , https://www.facebook.com/groups/mucugi/

Hi Jan, For license question, I would suggest you make a phone call to Microsoft directly: In the United States, call (800) 426-9400. In Canada, call (877) 568-2495. http://office.microsoft.com/en-us/exchange/exchange-server-licensing-licensing-overview-FX103746915.aspx Frank Wang TechNet Community Support
