A Microsoft file hosting and synchronization service.
Microsoft cannot find a simple fix for a search issue. It's just unbelievable. Well, I can't continue paying for something that doesn't work. Good luck everyone. My patience has run out with Microsoft. Google drive and Linux here I come! :)
Someone found a simple fix: Change Password.
I didn't change my password (using 2-factor authentication anyway) but I "changed my first name and last name" and search is back ...
Maybe a logout and logging in again will do the trick as well?
Looks like it has to do something to do with the "Microsoft Account" ...
It is just crazy that it took months ...
