Exchange Server 2019 reports wrong version

Question

Hi

After upgrading our Exchange Server 2019 infaestructure to CU8 the reported version running PS Get-ExchangeServer command was Version 15.2 (Build 792.3) but, after applying KB5000871 patch our servers continue to report Version 15.2 (Build 792.3) instead of Version 15.2 (Build 792.10). Is this a known behavior?

Thank you very much.

Kind regards,
Miguel Silva

Yes, that doesn't report the correct Exch Binary version, just the latest CU version.
Use this to verify instead:

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

Now check the returned value against Table 1 to validate that you’ve got the right file version.
