Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hello ÂKlaire Vatsika,
Thank you for posting your question in the Microsoft Q&A forum.
First, I’m really sorry for the time you have lost and for the run‑around you’ve experienced. Getting stuck in an MFA loop with no way to sign in is incredibly frustrating, especially when billing is about to start.
For your issue about the family account, unfortunately, you can’t add a business (work/school) license into a Family subscription, and the identities are separate by design, which often confuses the setup.
On the other hand, regarding to the issue about MFA loop, you will need to contact the Microsoft Data Protection team for further assistance. Please locate the appropriate support phone number for your country or region and contact Microsoft Support so the frontline team can raise a service request on your behalf: Customer service phone numbers
When calling the support number, the experience may vary depending on your country or region:
- In some regions, you may hear an automated message for approximately 30 seconds. You can ignore this message and wait for the prompt, then select “1” for Business email user and “1” again for technical support.
- In other regions, you may be guided through an automated conversation similar to the following:
- The system asks what issue you are experiencing → Authenticator
- Product in use → Office 365 for Business
- Account type → Company account
- Administrator status → Yes
- Are there other administrators in the organization? → No
- Proceed to create a service request → Yes
Alternatively, if you are unable to reach support by phone, you may create a temporary trial tenant to submit a support request for the block access tenant through the Microsoft 365 admin center. You can start with a trial license here: Microsoft 365 Business Plans and Pricing | Microsoft 365
Important: Please remember to cancel the trial subscription after your original account issue is resolved to avoid any future charges.
Note: Please understand that as a forum moderator, my primary goal is to provide helpful guidance and support through general troubleshooting steps. While I don’t have access to internal systems or test devices required to resolve backend/account issues, I truly appreciate your understanding of these limitations.
Thank you for choosing Microsoft, and I am looking forward to your response. If anything is unclear, please don’t hesitate to reach out to me.
