How to get Exchange server version numbers

It is important that “ALL” exchange servers in your environment run the same built version. One of the first things I check before starting any troubleshooting.

You get the installed version of exchange on your environment using exchange management shell using command “Get-ExchangeServer” as following

“Get-ExchangeServer | Format-List Name, Edition, AdminDisplayVersion”

Or

GCM exsetup |%{$_.Fileversioninfo}

The following table shows the build numbers and general availability dates for each version of Exchange 2016.
