Important – We’ve released version 12.8 to replace versions 12.3 and 12.1 of the calculators due to bugs found. Please download the latest version.

That’s right, there are some serious updates to the Exchange 2010 Mailbox Server Role Requirements Calculator, including one piece of functionality that you all have been asking for since I released the first version back in November!

Please go to our Mailbox Server Role Storage Requirements Calculator updates tracking page to see what is in this new version!

A blog post explaining the calculator (updated for this new version) is here and or you can download the calculator directly.

Comments welcome!
