Find Exchange version with PowerShell

Let’s find out the Exchange version with PowerShell.

• Run Exchange Management Shell as administrator.
• Type the following : Get-ExchangeServer | Format-List Name, Edition, AdminDisplayVersion
  As you can see from the below output, it includes the server name, the edition of the Exchange Server and the version number along with the build number.
  

However, if you’ve installed an Exchange Security Update, how can you determine which specific Security Update is applied to the Exchange Server? The previously mentioned cmdlet won’t provide that information. Let’s delve deeper into this matter.
Paste the script provided below into the Exchange Management Shell, and the resulting output will display the build number of the Exchange Servers:
$ExchangeServers = Get-ExchangeServer | Sort-Object Name
ForEach ($Server in $ExchangeServers) {
Invoke-Command -ComputerName $Server.Name -ScriptBlock { Get-Command Exsetup.exe | ForEach-Object { $_.FileversionInfo } }}

Now that we know the Exchange version and build number, we can find the product name, the Cumulative update installed and more details.
