Maybe this scenario is covered somewhere, but I can't find it. Here goes. I have an existing Windows Essentials Server 2012 server and domain in place. I want to add a second server (Windows Server 2012 R2) with Exchange 2013 residing on the new second server. There are a number of questions I have about this configuration. First off, how are user CALS handled? What is recommended for server roles, existing server and added exchange server? Please advise about any other issues I haven't thought of.
Thanks
