I know of at least 8 helpdesks that got hammered because of this today.
Got nailed myself. When opening any office app, it redirected to
office365 to pay / sign up, or enter a key.
Seems to be this It ran automatically around 00:09 on a Windows 11
system I have.

Since I use "permanent" versions of Microsoft Office from the 'olden days', where 2010 is my most recent from a college kid who had a $10 school offer,
I looked a bit into this to see if it was real, and, apparently it is real.
Apparently IT forums, Reddit, and Microsoft's own Q&A boards were flooded with reports from system administrators and individual users whose permanently activated, non-subscription versions of Microsoft Office (such
as Office 2016 and Office 2019) suddenly lost their activation status.
Opening Word or Excel abruptly shoved a paywall or a sign-in prompt in
front of users, telling them to buy Microsoft 365 or enter a product key.
While we often joke that Microsoft purposely tries to force people off perpetual licenses and onto recurring Microsoft 365 subscriptions, this specific incident seems, to me, and others, that it was a botched update.
The culprit tracked by users was apparently tied to automated Click-to-Run update behaviors/packages (such as components related to KB5002907).
As far as I can tell, the patch mistakenly "nuked" or failed to read valid local lifetime product keys, dropping Office into an unlicensed state.
Evidence that it was a bug rather than an intentional feature is that re-entering the original product key or logging back into the associated account successfully forced the software to recognize the license again.
Apparently, the bowling trophy Paul awarded the Microsoft employee who handled this is well deserved as their update code broke validation logic.

Whilst you are sorting this all out, recommend LibreOffice
to get them going again. They probably won't like it, muscle
memory and all, but at least it will get them going again.
