Exchange Server Sizing

Exchange 2016 having only one Server roles which is taking care of all Exchange components so it means hardware sizing is the most critical part of deployment. We can use the Exchange 2016 server requirement calculator , which will give us clear way to implements the Exchange server in existing environment.

Updating Existing Environment
