Fuck Microsoft. I know that everyone knows this already, but this is even more fucking stupid. And I just recently complained about even trying to log into a Microsoft account too.
Part of the rustle is just having to help people with computer shit, but let's ignore that. Let's also ignore the multiple "that account doesn't exist" errors that logging into a Microsoft account entails. That's enough for a rant right there.
Friend has a Microsoft 365 subscription (Excel, Word, etc.). His dad also has one that just expired. They realized they could just combine and use one instead of paying for both, since you get something like 5 or 6 total installs out of a subscription.
Long story short, no matter what I do, whether it be deleting credentials, modifying the registry, completely uninstalling Office 365, even reinstalling fucking Windows itself, the minute the dad accepts the invite to join his son's subscription and signs in with his Microsoft account, it pops up and says that his (old) subscription has expired and he needs to re-up. It will not validate his install with the son's subscription, it just says his shit is expired. It will not allow me to get rid of the expired subscription no matter what I try. I did everything the internet suggested except just making him an entirely new Microsoft account, because apparently he has other shit tied to the existing one (no idea what), and you can't have two different accounts operating at the same time on the same computer. Once you sign in as one, it flips ALL of your Microsoft logins to that one.
Perhaps it is due to the subscription expiring less than a month ago and we just have to wait, but I kind of doubt it. I told them they can deal with Microsoft customer support and try to get it fixed, I'll fucking explode if I talk to them.
I almost just used the MAS activation script, but that would likely backfire on me at some point and I don't want to deal with explaining to them what that is all about.
Fucking Microsoft. I'd press a button to kill them all, right now.
