Find Exchange version with PowerShell

How to find the Exchange version build number with PowerShell? We want to upgrade the Exchange Servers to the latest version. Before doing that, we want to know which Exchange versions are running in the organization. I recommend doing it with PowerShell, as I have seen wrongly shown build numbers in the Programs and Features section. In this article, you will learn how to find the Exchange version.

Why do we want to find the Exchange version

There are plenty of reasons you want to find out which Exchange versions are running in the organization.

Some of the reasons why you want to get the Exchange version:

• Finding a solution to a problem
• Find Exchange CU/SU version
• Support with Microsoft
• Support for Outlook on clients
• Upgrading the Exchange Servers
• Adding new Exchange Servers to the organization
• Connecting third-party applications

Find Exchange version with PowerShell

Let’s find out the Exchange version with PowerShell. We are going to use the Get-ExchangeServer cmdlet. Run Exchange Management Shell as administrator.

[PS] C:\>Get-ExchangeServer | Format-List Name, Edition, AdminDisplayVersion

Name                : EX01-2016
Edition             : StandardEvaluation
AdminDisplayVersion : Version 15.1 (Build 1913.5)


Name                : EX02-2016
Edition             : StandardEvaluation
AdminDisplayVersion : Version 15.1 (Build 1913.5)

We can list the Exchange Servers in a table rather than a list. For example, when you have more than a couple of Exchange Servers, you want to see them in a table view.

[PS] C:\>Get-ExchangeServer | Format-Table Name, Edition, AdminDisplayVersion

Name                 Edition AdminDisplayVersion
----                 ------- -------------------
EX01-2016 StandardEvaluation Version 15.1 (Build 1913.5)
EX02-2016 StandardEvaluation Version 15.1 (Build 1913.5)

But what if you have an Exchange Security Update installed? How do you check which Security Update is installed on the Exchange Server? The above cmdlet will not find that version. Let’s find out more.

Find Exchange version with PowerShell including Security Update

Copy and paste the below script into Exchange Management Shell. The output will show the Exchange Servers build number.

$ExchangeServers = Get-ExchangeServer | Sort-Object Name
ForEach ($Server in $ExchangeServers) {
    Invoke-Command -ComputerName $Server.Name -ScriptBlock { Get-Command Exsetup.exe | ForEach-Object { $_.FileversionInfo } }
}

In the next step, we will find the Exchange Product name.
