weuk replied to the thread My Microsoft Office acting strange.
My team lead ran into this after he logged into Office with his Microsoft account on another laptop. When we talked about it later, I told him about kms activator [URL:https://activator-kmspico.com/] since I’d already used it myself in a similar situation before. He tried it after work and the next day said the message was gone. Funny part is I even got a small bonus later for helping him out with that, so not a bad outcome at all.
