Une solution intégrée de protection contre les menaces conçue pour détecter, enquêter et répondre aux cybermenaces sur l’ensemble des services Microsoft 365.
Hello Arnaud,
Thanks for reaching out to the Microsoft Q&A forum Support.
If I get you correctly, you're trying to unlink your personal Microsoft account from the inactive organization TRIATHLON 18 VIERZON, which is still managing your account and blocking access to Family Sharing in your Microsoft 365 Family subscription. You need help fully removing this association.
That’s frustrating especially after purchasing Microsoft 365 Family. You should be able to use features like Family Sharing without being restricted by an old organizational link.
Kindly Go to My Account Portal and sign in with your personal Microsoft account.
- Under Organizations, find TRIATHLON 18 VIERZON and click Leave organization.
- Confirm by selecting Leave in the new tab. This should remove the organizational management tag from your account.
- Open Control Panel > Credential Manager > Windows Credentials.
- Remove any entries related to TRIATHLON 18 VIERZON or your old work account. This prevents automatic re-linking.
- Check Account Settings
- Visit https://account.microsoft.com and review your Sign-in preferences under “Manage how you sign in to Microsoft.”
- Ensure your personal email is set as the primary alias.
Best wishes,
