Changing between multiple Microsoft Teams accounts within the app or browser
This usually happens because the personal Microsoft account and the work or school account are separate identities, even if they use the same sign-in address. If the currently selected identity does not have access, the account switch fails.
Try this end-to-end reset:
- Close all browsers and apps that might be signed in to Microsoft services.
- Open a private or incognito browser window.
- Go to
https://aka.ms/vssignout. - Wait for the sign-out to complete. If it takes longer than a minute, close the browser and try again.
- Sign in again and select the other identity, choosing the work or school account instead of the personal account.
If the switch still does not complete, single sign-on in the Microsoft Entra tenant can keep the current account signed in. In that case, use a different browser or another incognito window, then sign in with the work account and try the switch again.
If this is happening in Teams and the app shows the personal account instead of the work account, sign out completely and sign back in with the work or school account.
