Teams - another user appears in my 'account and orgs'

To remove a user from your organization in Microsoft Teams, you typically need to be an administrator. Here are the steps you can follow:

1. Access the Admin Center: Log in to the Microsoft Teams admin center.
2. Navigate to Users: Go to the Users section where you can manage user accounts.
3. Find the User: Search for the user you want to remove.
4. Remove the User: If you have the necessary permissions, you should see an option to delete or deactivate the user account.

If the user was added as part of a group, you will need to remove them from the group in Microsoft Entra ID to effectively remove them from Teams. Note that simply removing a user from a team does not remove them from the organization itself; that requires admin privileges.

If you do not have the required permissions, you may need to contact your organization's administrator for assistance.

Thanks for sharing the details, Andy! You were guest-added to their organization

This is why you see them, but you cannot remove them, because you are not their admin. You are seeing the external organization you were invited into, not a user inside your Microsoft 365 tenant.

How to Remove That Random Organization From Your Teams Account

This removes the user/org from your Teams accounts list without needing admin permissions.

Microsoft allows users to remove themselves from any external directory.

Steps:

• Go to: https://myaccount.microsoft.com/organizations
• Sign in with your Teams/Microsoft account.
• You will see a list of organizations you’re a guest in.
• Find the unknown org or random user’s tenant.
• Click “Leave organization”.
• Confirm the warnings and click Leave.

After this:

• The org disappears from Teams.
• The random “user” won’t show in your account/org list anymore.
• You won’t be a guest in their directory.

See if this helps. If you need further assistance just let me know.
