It’s been a long road, but the initial release of the Exchange 2013
Server Role Requirements Calculator is here. No, that isn’t a mistake,
the calculator has been rebranded. Yes, this is no longer a Mailbox
server role calculator; this calculator includes recommendations on
sizing Client Access servers too! Originally, marketing wanted to brand
it as the Microsoft Exchange Server 2013 Client Access and Mailbox
Server Roles Theoretical Capacity Planning Calculator, On-Premises
Edition. Wow, that’s a mouthful and reminds me of this branding parody. Thankfully, I vetoed that name (you’re welcome!).
