Hello,
Is it possible in Excahnge 2013 like it was in 2010 to mix and match Exchange versions between the mailbox and client access roles? Right now I am looking at using the enterprise version on the mailbox servers since I will be creating more than the default 5 databases. But I just want to use the standard version on my client access servers since I have a role separated deployment.
I have been looking online but cannot fine a definite answer to my question saying explicitly that yes I can do that or no I can no longer do it. Checking the official licensing page for Microsoft does not state that you can one way or another.
