    Hi Alex,

    Thank you for taking the time to share detailed information about your situation.

    Just to gently clarify before we go any further, I do not have the ability to access, modify, or recover user accounts. Due to Microsoft security and privacy requirements, issues such as sign in failures, password recovery, and multi factor authentication can only be addressed by Microsoft’s dedicated Data Protection support teams, who have the appropriate tools and authorization to manage account level settings securely.  

    Since you are the only administrator of your tenant and you’re currently unable to sign in, the next essential step is to involve the Microsoft Data Protection team, as they are the only team authorized to help recover an admin account in these circumstances.

    You can reach out to Microsoft Data Protection team by: 

    Option 1: Contact Microsoft Data Protection Support by Phone (Primary Method)         

    You can start by calling your regional Microsoft support hotline here: Customer service phone numbers - Microsoft Support and choose Work account.

    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.          

    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:         

    (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.)            

    IVR: What kind of problem are you concerned about?           

    You: Authenticator.           

    IVR: What kind of product do you use?           

    You: Office 365 for business.           

    IVR confirmation: education or company account?           

    You: For companies           

    IVR: Are you an administrator?           

    You: Yes.           

    IVR: Do you have another administrator in your organization?           

    You: No.           

    IVR: Do you need a... Service request?    

    You: Yes. I need to create a ticket. Please send me directly to the Data Protection Team.    

    Option 2: Create a Temporary Account (Trial Tenant) to Submit a Support Ticket (Alternative Method)     

    If you cannot reach a live agent, there is still a workaround that you might consider registering for a new tenant by signing up for a trial subscription. Once set up, you can access the admin console of the new tenant and submit a support ticket requesting to speak with the Data Protection team on behalf of your previous tenant. 

    To set up a new tenant, please follow these steps: 

    • Visit Microsoft 365 Business Plans and Pricing | Microsoft 365. This would allow you to create a new tenant following the prompts provided.
    • Follow the guided setup process to create a new account for a new tenant. 
    • Once your tenant is created, you should be able to access the support portal and submit your ticket referencing your locked account without further issues. 
    • To create a Support ticket: sign into Microsoft 365 Admin Center > Support > Help & Support. 

    In your ticket description, you'll need to clearly explain that you're trying to regain access to your previous Microsoft 365 tenant and need help from the Data Protection team. Here's a message you can use or adapt: 

    "Hello, I’m currently unable to access my previous Microsoft 365 tenant due to losing MFA access, which prevents me from receiving verification codes. I’m the global admin, but I’m locked out and unable to generate a QR code or bypass MFA. 

    I created this new tenant solely to request assistance. I kindly ask to be connected with the Data Protection team to verify my identity and help me recover access to the original tenant. 

    This is urgent, as I rely on Microsoft 365 for my work and have been unable to operate for several days. I’m available to provide any documentation or verification needed to support the recovery process."    

    Please remember to cancel the trial subscription after your issue is resolved, as this will help you avoid any accidental billing. You may prefer the following resource for detailed instructions: Cancel your Microsoft business subscription in the Microsoft 365 admin center | Microsoft Learn    

    I truly hope this helps you regain access to your account quickly. Even though I can't directly intervene, directing you to the correct and specialized support is the most effective help I can provide.     

    Thank you for your kindness and contributions to the forum.
