Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
I have recovered today the admin access. The Data Protection Team needs between 24 and 48 hours to process the MFA reset procedure. My conclusions :
- Prepare for a minimum of 24 hours of admin lockout.
- Microsoft Support can be effectively contacted from Monday to Friday.
- Mention "Data Protection Team" in order to escalate the case quickly and avoid delays in the process.
