Only global Administrator locked out MFA- need tenant recovery/data protection

Hello,

I am the only Global Administrator of my Microsoft 365 tenant and I have lost access to Microsoft Authenticator.

When I try to sign in, Microsoft only gives me the option to approve a notification in Authenticator or enter an Authenticator code. I no longer have access to that Authenticator registration, and there is no other authentication method available.

There are no other administrators in the tenant who can reset my MFA or authentication methods. My password is correct; the issue is specifically the MFA/Authenticator lockout.

I already contacted Microsoft support by phone, but the automated system was unable to complete the support request and redirected me to online support, which requires me to sign in to the locked administrator account.

I need assistance with tenant recovery / Global Administrator MFA reset and, if necessary, escalation to the appropriate Data Protection or account recovery team so I can verify ownership of the tenant and regain administrative access.

I can provide proof of ownership, billing information, domain verification, or any other information required through a private support channel.

Please do not ask me to reset the password, because I still know the password. The problem is access to the MFA method.

    Hi Elevar,

    Thank you for the clear explanation of your situation.  

    Since you have already contacted Microsoft Support but were unable to reach the appropriate recovery team, I recommend trying to contact Microsoft Support again using the prompts below to navigate the automated system. Several users who experienced similar tenant lockout situations have reported that this approach helped them get past the automated system and reach the appropriate support team. 

    Here are some tips and an example of a prompt to help you navigate the IVR more effectively:  

    (When you call the support number, you may hear an introduction of about 30 seconds such as "you can visit the link...". You can ignore this introduction and wait until you are presented with the options. Then press "1" as a business email user, and again "1" for technical help.)    

    In some regions, the initial interaction may be automated, so here’s a general idea of how the conversation might go to help you prepare:      

    • What kind of problem are you experiencing?         
    • Answer: Authenticator 
    • What products do you use?         
    • Answer: Office 365 for business         
    • Is this for an education or company account?         
    • Answer: For companies         
    • Are you an administrator?         
    • Answer: Yes         
    • Are there any other administrators in your organization?         
    • Answer: No. I am the only admin in my tenant          
    • Do you need a... Service request?          
    • Answer: Yes. I need to create a ticket. Please send me direct to the Data Protection Teams.      

    During the phone call, you will need to provide the information associated with your subscription, such as your company name, billing details, phone number, and an alternate email address, etc. This information allows the Data Protection team to verify your identity and securely assist you in regaining access to your administrator account.      

      

    I also recommend calling during business hours. In my experience, it can be difficult to get through to the correct support queue, and automated systems don't always work as expected. If you can't get through on your first try, I suggest trying again later or at a different time. 

      

    I know being locked out of the only admin account can be stressful, but contacting the Data Protection team is the correct path forward in this scenario. 

    I hope these steps help you create a support ticket successfully and move closer to regaining access to your administrator account. While I’m not able to intervene directly, guiding you to the right support team is the most effective help I can provide here.  

    Hope you're able to get this resolved soon.
