Issue Summary: I am the sole Global Administrator for my Microsoft 365 Developer E5 tenant, and I am currently locked out of my admin account due to a lost MFA (Microsoft Authenticator) device. While I have the correct password, I cannot fulfill the 2FA requirement.
Critical Impact: The tenant has 25 users and contains critical development data. As of today, the entire tenant (including all OneDrive accounts) has entered a Read-Only state. My Developer Dashboard indicates that the subscription is active and has been recently renewed, yet all "Write" access is restricted.te
Technical Details:
- Tenant ID: PII
- Primary Domain: iamvxxxxxnxxxxan.onmicrosoft.com
Account Type: Microsoft 365 E5 Developer (Sandbox)
Status: Subscription Active / Files Read-Only
Error: MFA Lockout (No alternative 2FA methods configured)
Request: I have tried calling the regional support line in India (+91 8000 404 454), but I am unable to get connected. I am requesting a Microsoft Moderator to initiate a Private Message so I can provide my contact details and have this case escalated to the Data Protection Team for an MFA reset and tenant recovery.
Thank you for your urgent assistance.

To resolve this, the recommended approach is to contact the Microsoft Data Protection team. You can reach them by calling Microsoft Customer Service using the phone numbers listed here: Customer service phone numbers - Microsoft Support.
If you have access to another tenant or subscription where you still have Global Administrator privileges, you may also raise a support request from there to get assistance in restoring access to the affected tenant.
For future reference and to help prevent tenant lockouts, please check: Preventing tenant lockouts - Microsoft Learn.
I understand you are not able to connect to support line number.
Please once try again and let me know the status so that I will help you further on this case.
