How to Remove an Old Teams Organization and Stop Startup Warnings
Question details
The user needs to remove an old Microsoft Teams organization from their personal account and stop recurring startup warnings.
- Product
- Microsoft Teams
- Device & OS
- not provided
- Scenario
- A personal Microsoft account is associated with a legacy Teams organization that is now paid, causing recurring warnings to pop up when the application starts.
- Observed behavior
- The user receives persistent warnings at startup and is unable to easily detach their personal account from the legacy organization within the Teams app.
Make sure you have your Microsoft account login credentials handy, and note that leaving an organization will permanently remove your access to any files or chats associated with it.
Manage and Leave the Organization via Microsoft Entra ID
Use the Microsoft Entra ID portal to manage organizations linked to your personal account and manually leave the unwanted one.
Since personal Teams accounts and organization administration are handled separately, you often cannot leave an organization directly from the personal Teams app interface. Microsoft Entra ID (formerly Azure Active Directory) provides the external management tools necessary for this action.
Open a web browser and sign in to the Microsoft 'My Account' portal (myaccount.microsoft.com) using your personal Microsoft account credentials.
Locate the account settings menu and click on 'Organizations' or 'Manage Organizations' to view all entities linked to your account.
Find the old Teams organization in the list, click 'Leave organization', and confirm your choice to remove it from your account.
Disable Microsoft Teams Auto-Startup
Prevent Teams from launching automatically when you turn on your computer to stop the recurring warnings from appearing.
Contact Microsoft Support Community
Reach out to specialized support if you are unable to remove the organization yourself due to backend permission restrictions.

Frequently Asked Questions
Why am I receiving startup warnings for an old Teams organization?
This typically occurs when your personal Microsoft account remains linked to an organization that has expired, transitioned to a paid tier, or been deleted without properly detaching your account first.
Can I leave a Teams organization if I don't have admin rights?
Yes, you can usually leave an organization as a guest by accessing the Microsoft 'My Account' portal and selecting 'Organizations'. However, if the organization's admin has locked guest departures, you will need to contact Microsoft Support for manual removal.
How do I stop Microsoft Teams from opening automatically on a Mac?
On a Mac, open 'System Settings', go to 'General', and select 'Login Items'. Find Microsoft Teams in the 'Open at Login' list and click the minus (-) button to prevent it from starting automatically.
