Additional sign-in or account-related issues within Microsoft Teams for business
Dear @Aaaaa
I recommend using the following steps, depending on the account you use in Teams:
For a personal Microsoft account:
- Open Teams on your computer or browser.
- Go to Settings > Accounts and orgs.
- Select Leave beside the organization.
- Follow the browser prompts and confirm Leave.
The change can take a few hours. Afterwards, sign out of Teams and sign back in.
For a work or school account:
- Open My Account — Organizations and sign in with the account used in Teams.
- Find the organization under Other organizations you collaborate with.
- Select Leave organization and confirm.
You cannot leave your Home organization yourself; its administrator must assist. Leaving another organization removes your access to its resources, so save anything you need beforehand
If Leave is missing or an error appears, please let me know whether you use a personal or work/school account and share the exact error, with personal details hidden.
