How to Report and Remove Unknown Guest Accounts in Microsoft Teams
Question details
The user needs to remove unrecognized guest accounts or organizations appearing in their Microsoft Teams profile to ensure account security.
- Product
- Microsoft Teams
- Device & OS
- not provided
- Scenario
- The user discovers unfamiliar guest accounts within their Microsoft Teams interface and wants to remove them to prevent potential unauthorized access.
- Observed behavior
- Unknown guest accounts remain visible in Microsoft Teams even after the user has changed their account password.
Verify whether the unfamiliar entries are actually Microsoft Teams guest accounts, or if they are simply backup verification email addresses linked to your Microsoft account security settings.
Leave Unrecognized Guest Organizations in Teams
If you have been added as a guest to an unknown organization, you can manually leave it through your Microsoft Account portal.
This method applies primarily to users who have been invited to an external Microsoft Teams organization and wish to sever the connection to protect their personal or work account.
Open your web browser and navigate to the Microsoft My Account portal (myaccount.microsoft.com), then sign in with your Teams credentials.
Click on the 'Organizations' tab from the left-hand menu to view all the organizations your account is currently linked to.
Locate the unknown guest account or organization in the list, click on 'Leave organization', and confirm your choice to remove it from your Teams interface.
Secure Your Account with Password and MFA Updates
If you suspect unauthorized access, immediately secure your Microsoft account by updating credentials and enabling two-step verification.
Contact Your IT Administrator or Microsoft Support
For work or school accounts, organizational policies might prevent you from removing guests yourself, requiring administrative assistance.

Frequently Asked Questions
Why do unknown guest accounts appear in my Microsoft Teams?
These accounts often appear if you were added to another organization's Teams tenant as a guest. Alternatively, they could be old backup email addresses mistakenly identified as guest accounts in your security dashboard.
Will changing my password automatically remove guest accounts from Teams?
No. While changing your password secures your account from future unauthorized logins, it does not automatically remove existing guest organizations or users already linked to your profile.
Can I remove a guest account if I am using a work or school Teams account?
In many work or school environments, guest account management is restricted by organizational policies. You will likely need to contact your IT administrator to have the guest removed via the Microsoft 365 Admin Center.
