HOWTO: Remove yourself from an external organization’s Microsoft Team

Have you ever belonged to another company’s Microsoft Team and then needed to remove yourself from that Team – and that organization entirely?

You can “Leave the Team” – and that process is pretty well documented.  But you’re still technically connected to that organization via Azure B2B and thus you’ll continue to see that organization listed within your “organizations” or tenants list within the Teams client.


What do I do with all these "XXXXXXXX(Guest)” organizations I still belong to?

How does one get rid of these entries?

The answer is a little more convoluted than it should be.  You basically have to go into the Azure Portal using your company/org account and remove yourself as an Azure Active Directory B2B guest of these tenants/orgs.

  1. In the Azure portal, click your name in the upper right and select View account.
  2. Open your Access Panel, click your name in the upper right, and next to Organizations, select the settings icon (gear).
        1. Note: If you’re not already signed in to the organization you want to leave, under Organizations, click the Sign in to leave organization link next to the organization’s name. After you’re signed in, click your name again in the upper right and next to Organizations, select the settings icon (gear).
  3. Under Organizations, find the organization that you want to leave, and select Leave organization.
  4. When asked to confirm, select Leave.
