New Sizing Calculator for Exchange Server 2019
For Microsoft Exchange Server 2019, the Exchange team unveiled a new sizing calculator. As with previous versions, it is a planning tool in the form of an Excel template file that helps determine hardware resource requirements for Exchange Server implementations. It is also announced that in the upcoming Cumulative Update 2 for Exchange Server 2019, the Sizing Calculator will become an integral part.
The new Sizing Calulator was designed exclusively for Exchange Server 2019 and does not provide references to older versions. The new tool supports deployment on Azure for the first time and is especially optimized for virtualized workloads.
