Well folks, this is an updated Calc for those who are looking at replacing their mail system with the superior Exchange or just need to know what else is needed to support the mighty Exchange environment.
Oh, and if you would like to know what the calculator is all about, you can read all about it here! I just downloaded it... I think their is one left.
We've released the Exchange 2013 Mailbox Server Role Requirements Calculator.
