A cloud-based identity and access management service for securing user authentication and resource access
Hello @Jose Mayorga,
Thank you for connecting offline.
Based on the affected user account details, when I checked on my end, I see there is another global admin present in your tenant on yahoo.com account. Using this account first we tried getting access to the tenant and reset the MFA for the affected accounts by following the below steps:
To manage user settings, complete the following steps:
1.Sign in to the Microsoft Entra admin center as at least an Authentication Administrator.
2.Browse to Identity > Users > All users.
3.Choose the user you wish to perform an action on and select Authentication methods. At the top of the window, then choose “Require re-register MFA” options for the user.
Then you can login back to any office application and register with new MFA auth method.
