Hello Exchange Team
same issues as chrlie when it comes to versioning of my Exchange 2016 CU23 Jan 2023 SU servers.
I used the newer, 'updated' Feb 2023 SU .cab file Exchange2016-KB5023038-x64-en.msp from the Microsoft catalog and installed it on my 4 servers and after rebooting here are the results (same results for all 4)

Your installer does indeed make an incorrect change to the serialNumber of each server as the whenchanged date corresponds to installation date and time for each server. Should I go ahead to change it to the proper Feb 2023 SU long format version which would be serialNumber : {Version 15.1 (Build 32507.021)} ?
what a mess ...
thanks
