Update: The old blog post has been updated to the following below:-

I have updated the article to include a PowerShell script that will give you all the information you need displayed in a Grid.

This script can be modified to add more build information which I will update overtime but includes CU23 for now. This is for Exchange 2016 Server Only and I will be doing the same for Exchange Server 2019.

Below is the output from the script:

    Exchange 2016:- find the cu installed on your server
    Exchange 2016:- Find the CU installed on your server 1

    Script:

    Here is the script that I will update overtime to include all the other CU’s etc.

    # Import the Exchange module
    Add-PSSnapin Microsoft.Exchange.Management.PowerShell.SnapIn
    
    
    # Define a hashtable with build numbers and corresponding product names
    $buildInfoTable = @{
        "15.01.2507.035" = "Exchange Server 2016 CU23 Nov23SU";
        "15.01.2507.034" = "Exchange Server 2016 CU23 Oct23SU";
        "15.01.2507.032" = "Exchange Server 2016 CU23 Aug23SUv2";
        "15.01.2507.031" = "Exchange Server 2016 CU23 Aug23SU";
        "15.01.2507.027" = "Exchange Server 2016 CU23 Jun23SU";
        "15.01.2507.023" = "Exchange Server 2016 CU23 Mar23SU";
        "15.01.2507.021" = "Exchange Server 2016 CU23 Feb23SU";
        "15.01.2507.017" = "Exchange Server 2016 CU23 Jan23SU";
        "15.01.2507.016" = "Exchange Server 2016 CU23 Nov22SU";
        "15.01.2507.013" = "Exchange Server 2016 CU23 Oct22SU";
        "15.01.2507.012" = "Exchange Server 2016 CU23 Aug22SU";
        "15.01.2507.009" = "Exchange Server 2016 CU23 May22SU";
        "15.01.2507.006" = "Exchange Server 2016 CU23 (2022H1)";
        
    }
    
    # Function to get product name based on build number
    function Get-ProductName($buildNumber) {
        if ($buildInfoTable.ContainsKey($buildNumber)) {
            $buildInfoTable[$buildNumber]
        } else {
            "Unknown Product"
        }
    }
    
    $ExchangeServers = Get-ExchangeServer | Sort-Object Name
    
    # Create an array to store the results
    $results = @()
    
    foreach ($Server in $ExchangeServers) {
        $serverName = $Server.Name
        $edition = $Server.Edition
    
        # Get Exchange version using Invoke-Command
        $version = Invoke-Command -ComputerName $Server.Name -ScriptBlock {
            Get-Command Exsetup.exe | ForEach-Object { $_.FileVersionInfo.FileVersion }
        }
    
        # Get product name from the local table
        $productName = Get-ProductName $version
    
        # Create a custom object with the information
        $resultObject = [PSCustomObject]@{
            ServerName   = $serverName
            Edition      = $edition
            Version      = $version
            ProductName  = $productName
        }
    
        # Add the result object to the results array
        $results += $resultObject
    }
    
    # Display the results in a grid
    $results | Out-GridView
    

    It takes a few seconds/minutes to run, all depending on the number of servers it has to query.

    Hope it helps.
