Win11 24H2 and MS Office Activation

Both my HP machines updated to 24H2 on New Years Eve. They both have Office Professional 2021 and Adobe Acrobat Pro installed. Update went fine but Office said it was not activated after 24H2 installed. I was able to activate both machines again but just seems weird. Anyone experience this?

I was surprised to see how many people are complaining about Microsoft Activation Servers and having Windows 11 deactivated. I haven’t yet come across anything about Office or Acrobat but undeniably, there seems to be a problem.

I simply Googled “Microsoft office needed to be reactivated after 24H2” and was shocked, it goes on and on.

I did for Office Professional 2021 right after New Years, and my PC is still on 23H2. Had to reactivate using PowerShell. I'm using the LTSC, so I'm not sure how long the licensed activation key I used was valid for; or maybe it could have been a server issue. Either way, I was locked out of Outlook until I changed the key.
