Build Number Not Updating

Question

Exchange 2016 CU23.&nbsp; The build number shows as 15.1.2507.17 in both Exchange Admin Center and Exchange Management Shell.&nbsp; I have installed 4 SU's since installing .17 (.21, .23, .27, .32).&nbsp; They all show in Windows Updates Install History.&nbsp; It looks to me like my current build should be 15.1.2507.32.&nbsp; Has anyone encountered this?

HealthChecker also shows the version at 15.1.2507.032.I am thinking I am safe to remove all of the large files that correspond to the previous versions.Thank you for your help.

File Version 15.1.2507.32Product Version 15.01.2507.032Any way to get Admin Center and Management Shell to reflect that version?My reason for looking into this in the first place is that I want to delete some large files that look like they are specific to each version. I want to make sure it doesn't break anything if they are still being referenced.C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\Owa The directories are named 15.1.2507.17, .21 etc.THANKS!

That would make sense, but at the moment we are out of luck. Microsoft have outlined how to get the version of Exchange in the below link, but none of the include the EAC!https://learn.microsoft.com/en-us/exchange/new-features/build-numbers-and-release-dates?view=exchserver-2019#view-the-build-number-of-an-exchange-based-server

I have an Exchange 2019 server, My question is why the Build number has not changed after installing the Exchange CU14 SU1 (KB5036401) update successfully on the server it still shows an older build number Version 15.2 (Build 1544.4) instead of 15.2.1544.9
