Dear Friends,

I am using One Exchange 2010 Server Standard with 100 Exchange 2010  CAL Standard Licenses, i have requirement for more licenses, i understand There is no limitation in Microsoft Exchange to add more users even though we have only 100 licenses.

But to have compliance with Agreement of Microsoft i would like to buy.

NOW IF I BUY EXCHANGE 2013 CAL Licenses, can i use that in Exchange 2010 Server Environment (I mean from Microsoft Compliance prospective), One of the Customer Desk Executive of Microsoft said NO....Kindly Confirm.
