Exchange 2013 CU 23 after instalation of KB5000871 still show version 15.0.1497.2

Question

I've Exchange 2013 CU23

I've installed successfully KB5000871 - it is listed here:

Get-ItemProperty HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName
Security Update for Exchange Server 2013 Cumulative Update 23 (KB5000871)

And I can see it under Control Panel > Programs > Programs and Features > Installed Updates.

However in Exchange PowerShell shows version 15.0.1497.2 - while as far as I know - it should be 15.0.1497.12

[PS] C:\Windows\system32>Get-ExchangeServer | select AdminDisplayVersion

AdminDisplayVersion
-------------------
Version 15.0 (Build 1497.2)

Answer 1

The AdminDisplayName reflects the CU version , not the version with the patch applied.

If that command shows 15.00.1497.012, then you are good!

Answer 2

Check the version using these steps:
https://learn.microsoft.com/en-us/exchange/troubleshoot/client-connectivity/exchange-security-update-issues#verify-the-installation-of-cus--sus

Get-Command Exsetup.exe | ForEach {$_.FileVersionInfo}  

For CU23: 15.00.1497.012

Answer 3

Thanks, Andy for a fast response.

FileVersion is:

Get-Command Exsetup.exe | ForEach {$_.FileVersionInfo}

ProductVersion   FileVersion      FileName
--------------   -----------      --------
15.00.1497.012   15.00.1497.012   C:\Program Files\Microsoft\Exchange Server\V15\bin\ExSetup.exe

I've restarted this server after the installation of this patch. So - not sure why Exchange itself still shows .2 - also in WebGUI

Answer 4

Ok, sounds reasonable :)

Thanks mate!
