Licenses Required for New Exchange 2010 Front-End with Exchange 2003 Back-End
Posted on 2010-08-22
We currently have an Exchange 2003 server with the necessary CAL's (no software assurance). We want to add an Exchange 2010 front-end server to take advantage of Outlook Web App. I know I have to buy a server license, but do I have to buy Exchange 2010 user CAL's as well even though we already have CAL's for the 2003 back-end and this 2010 server will only be a front-end? I'm guessing I do, but I wanted to ask. Links to Microsoft documentation would be appreciated.
