How to view the version and build number of a Microsoft Exchange Server

Applies to: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016

To view the version and build number of a Microsoft Exchange Server run the following command in the Exchange Management Shell

[PS] Get-ExchangeServer | Format-List Name, Edition, AdminDisplayVersion, ServerRole

But what if you don't have easy access to EMS, or you want to check the version of the Exchange Server your mailbox is hosted?

If your on-prem Exchange 2013/2016 organization is using MAPI over HTTP (and you really should be) you can use the following URL to check which version of Exchange is running on the server hosting your mailbox:

        https://<serverFQDN>/mapi/emsmdb/

 

For Office 365 use:

         https://outlook.office.com/mapi/emsmdb/

Note: this method won't work if you haven't configured MAPI/HTTP or for mailboxes hosted on Exchange 2010 or earlier because they don't support MAPI over HTTP.
