Sole Global Admin locked out — MFA reset needed, automated support disconnecting repeatedly (11+ days, no case number)

Question

Hello,

I work for a managed service provider based in Tonga (TokoWireless Ltd, trading as WanTok Tonga) and manage a Microsoft 365 tenant on behalf of a client. I am the sole Global Administrator on that client tenant and have lost access because Multi-Factor Authentication was configured via Microsoft Authenticator on a phone that has since been damaged and is no longer accessible. There is no other Global Admin on that tenant able to reset MFA for me.

I have attempted to resolve this through Microsoft support at least three times over the past two weeks (including twice on 27 August 2026) via the New Zealand regional support line, and on each occasion the automated call system disconnects shortly after saying it will verify my email — no case number or follow-up email has ever been received. I also tried the Support Assistant chat, which offered only general self-service steps that don't apply (since there's no other admin to act on my behalf) and then closed the conversation without opening a case.

It has now been 11+ days with no case number, no verification email, and no path forward through the automated channels. Could a moderator help get this escalated to the Microsoft 365 Data Protection / tenant recovery team? I'm happy to provide tenant ID, locked admin account's UPN and further details via private message.

Hi @John Liavaa

It seems you have already attempted to contact Microsoft Support several times but have been unable to get past the automated system.

If you have not already tried it, you could use the following script as an example:

Q. Can you tell me if you are calling as a home user who uses a product or service at home or a business user who uses it in your business to provide the best assistance? 
A.I am a business user. 
Q. Thank you. Can you give me the details of your inquiry? 
A. Login technical support. 
Q. First of all, can you tell me which products you are inquiring about today? 
A. Microsoft 365 business Standard。 
Q. Please wait a moment, I understand Microsoft 365. Are you calling about a new case or an existing one? 
A. New. 
Q. To receive phone support, your phone number must be associated with your Microsoft 365 admin profile. To do this, go to aka.ms/m365profile. Again, it aka.ms/m365profile . This can take 48 hours. In the meantime, you can go to aka.ms/m365profile and file a case online. If you prefer, you can also text the link to the phone number you are calling. What do you think? 
A. The phone number is already linked to the link. 
Q. Can you tell me about the products in your inquiry? 
A. Microsoft 365 Business Standard. 
Q. Are you a Global Administrator? 
A. That's right. 
Q. I'm sorry. I didn't understand. Are you a global administrator for your domain? 
A. Yes, I am a global administrator for the domain. 
Q. If you have any inquiries, you can contact a Microsoft representative. Are you sure? 
A. Yes. Please. 
Q. Yes, I understand. Please wait a moment.

 In case the phone line is not supportive, you can consider directly submitting a support request as a helpful workaround:    

-Create a temporary Microsoft 365 tenant using a trial license: Go to Microsoft 365 Business Plans and Pricing and click Try for free to set up a temporary Microsoft 365 tenant with a trial license.    

-Use this new account to sign in to the Microsoft 365 Admin Center and submit a support request on behalf of your primary (locked) account.   

-Click Help & Support > then choose Create a support request.    

Note: This method doesn't require you to use your new account for your business. Instead, it allows you to create a temporary global administrator account so you can submit a support request, as your original global administrator account is locked out due to issues with multi-factor authentication. The trial account is free for one month. Be sure to delete it after submitting your support request to avoid any automatic renewals or charges from Microsoft.     

For further instructions, you can follow this guide: Get support - Microsoft 365 admin | Microsoft Learn.   

Since this is a user-to-user support forum, I do not have access to internal databases or the ability to escalate cases directly to Microsoft’s internal teams. Therefore, please kindly contact the Microsoft Support team for the most efficient help.
