if you cannot log in, it could be that Teams is trying to authenticate your user to the wrong endpoint:

personal accounts ("Live ID") has a different authentication endpoint as your work account.

if you used a personal account with microsoft apps on macos, it starts adding them to other services. when you open a Microsoft app, it can happen that it starts to try your authentication to a different endpoint, resulting in login errors (user does not exist / not found)

if that is your case, try to remove / log out other accounts to ensure, this can't happen. try to split usage, e.g. by starting to only use your live id in browser.

I have the same problem, because I used my LiveID in OneNote. I also have the issue, that in some services it now tries to pick the wrong account.

I also have a similar issue on iPhone - it always tries to take my LiveID for OneDrive, thus I can not open shared files, etc. or app restarts because it reapplies company policies to the app.

I think this is by design.. but it can be very annoying and frustrating.

Hi @steven foulkes

Could you first confirm whether this issue occurs when you're signing in with a work or school account? If so, are you using the Copilot app for macOS? If the app redirects you to the browser for sign-in, you may be using the consumer Microsoft Copilot app. To sign in with a work or school account on macOS, you should use the Microsoft 365 Copilot app instead.

You can download it here: Download Microsoft 365 Copilot App on Windows, Mac, Android & iOS

If this isn't your scenario, could you provide a few more details?

Are you using Copilot in a web browser or the Copilot app for macOS?
Which browser are you using (Safari, Chrome, Edge, etc.)?
Does Copilot sign you out after a period of inactivity, or are you unable to sign in at all?
When you try to sign back in, do you see an error message, a blank page, or does it simply return you to the sign-in screen?
Have you already tried clearing your browser cache/cookies or testing in an InPrivate/Incognito window or a different browser?

Please know that while our initial response might not resolve the issue right away, your input is incredibly valuable. With a bit more detail, we’ll work together to find the best solution for you.
