Hi Eric,
I'm still getting messages from windows complaining about the account even after I deselected to show me Office.com files.
This message is really bugging me and the account they are asking for is the same that File Explorer was complaining about. How to remove the account (work account from previous job) for good on my computer so that no other application in the windows 11 environment requests it?
Try the "Accounts > Access work or school" settings page. If you're like me, you might find an old no-longer-used account that you can disconnect!
