Whenever there's an update, I can't sign into Microsoft 365 on my Mac.

I prefer to use a password or have the code emailed to me and choose 'sign in another way'.

After I enter the code or password, I get this error message.

    I fixed it. I don't know exactly how, but it works now. I have automatic updates set up. I did lose two days worth of work though. Even though autosave was on, it wasn't working.

    Which version of macOS do you have? If you have an older version, you may not be able to run the most recent release of Microsoft Office.
