Cannot remove organization in Teams

Question

Cannot remove organization in Teams

JessL 0

I have been added to Microsoft Higher Education community teams some years ago and it has been showing as an organization (Microsoft) in Teams.

I can no longer sign in to this, I get an error that my account is locked and our administrator says that the error messages received from the guest org is The guest user account is disabled. and User Account is not found for Fido Sign in flow.

I cannot leave the Microsoft-organization, because when I click on leave (under https://myaccount.microsoft.com/organizations) I am asked to sign in.

I tried sending an e-mail to the team [Moderator note: Personally Identifiable Information removed]@microsoft.com, but I get a delivery failure "access denied"

Dear @JessL

I understand the issue. The key error here is “The guest user account is disabled”, which indicates that your guest account in the Microsoft Higher Education community’s tenant is disabled. The additional “User Account is not found for FIDO Sign in flow” message is also consistent with the guest account no longer being able to complete authentication.

Because the Leave organization action at https://myaccount.microsoft.com/organizationrequires you to authenticate to that organization first, you may not be able to remove the organization yourself while the guest account is disabled.

In this situation, I recommend contacting the administrator of the Microsoft Higher Education community tenant and asking them to either:

Re-enable your guest account temporarily, so you can sign in and leave the organization yourself; or
Remove/delete your guest account from their tenant directly.

Since the @microsoft.com address is returning “Access denied,” you will need to use another support/contact channel for the Higher Education community or Microsoft tenant administrators. Your own organization’s administrator generally cannot re-enable or remove a guest object that belongs to the external tenant.

If you no longer need access to this community, having the guest account removed from the Microsoft tenant is the cleanest solution. Once the guest account is removed, the organization should no longer remain associated with your account.

I would not recommend repeatedly attempting to sign in or reset FIDO/Authenticator on your side, because the underlying issue is the disabled guest account in the external tenant, rather than simply a problem with your local Teams application.

Thank you very much for your reply!

This is what I suspected, but the problem is I have no contact information to the Higher Education community or Microsoft tenant administrators...

Dear @JessL

You’re very welcome, and I understand the difficulty here. If you don’t have any contact information for the Higher Education community administrators, and @microsoft.com is no longer accepting messages, there is unfortunately no self-service method I can recommend to bypass the disabled guest account and remove the organization.

At this point, I would suggest contacting Microsoft Support and explaining that:

Your personal/work account is still associated with the Microsoft Higher Education community tenant as a guest.

The guest account in that tenant is now disabled.

You cannot sign in to the guest organization.

You cannot use My Account > Organizations > Leave because that action requires authentication to the disabled guest account.

The community contact address (@microsoft.com) returns Access denied.

Ask Microsoft Support whether they can route the case to the appropriate team or tenant administrators for the Higher Education community and have the obsolete guest account removed.

As an Independent Advisor, I don’t have access to Microsoft’s internal tenant administration systems, so I cannot remove the guest organization directly or identify an internal administrator for that tenant.

If Microsoft Support cannot assist through the normal support channel, I would also recommend mentioning specifically that this is an external/guest tenant association that cannot be removed because the guest account is disabled. That should help them understand that this is different from a normal Teams sign-in problem.
