    Hi @Rakesh Jayswal,

    Thank you for posting your question in the Microsoft Q&A forum.      

    I’m very sorry to hear about your situation. Regarding that there is no admin account for you tenant. I’d like to ask a quick questions to better understand your situation and assist you effectively:     

    Do you have any other admin account that you can use to log in to Microsoft 365 Admin center?   

    If you don't have any other admin account in this situation, the Microsoft Data Protection team has tools and processes in place to verify identity and regain access to administrator accounts.    

    Please note that forum moderators have no control over user accounts, especially when it comes to logging in to your account, resetting your password, changing your access, etc.    

    Therefore, If you are the only administrator in your organization,  then you need to involve Microsoft data protection team. Please try to find the related hotline number to call the frontline let them raise a ticket for you: Customer service phone numbers - Microsoft Support 

    *(Important Note: Depending on your country or region, 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 countries, this is an automated conversation: First, when you call the hotline, they will ask you what kind of problem you are struggling with.    

    Answer: Authenticator.    

    A: What products do you use?    

    B: Office 365 for business.    

    Verification: Education or company account?    

    B: For companies    

    A: Are you an administrator?    

    B: Yes.    

    A: Are there any other administrators in your organization?    

    B: No.    

    A: I need one.... Service request?    

    B: Yes    

    If your organization's Office 365 Business/Education subscription is from a partner or reseller, and the global administrator is unable to open a service request on your end, contact the reseller's support provider to help open a service request on behalf of you instead.    

    Alternatively, you can try set up a new trial tenant and submit your support request:   

    1. Visit the Microsoft 365 Enterprise Plans page: Go to Compare Office 365 Enterprise Pricing and Plans | Microsoft 365.   
    2. Choose a plan and start a free trial: Select any of the available plans and click "Try for free" to begin the trial setup process.   
    3. Follow the guided setup: Complete the steps to create a new Microsoft account and a new tenant. This will be a separate and independent Microsoft 365 environment.   
    4. Access the Microsoft 365 Admin Center: Once the new tenant is created, navigate to https://admin.microsoft.com/.   
    5. Go to Support: In the left-hand navigation menu, click on "Support" and then "Help & support."   
    6. Raise a support ticket: Describe your issue in detail. Crucially, you must clearly state that you are locked out of a different, pre-existing Microsoft 365 tenant where you are the administrator. Provide the following information about your locked account:    
      • Your administrator account email address for the locked tenant.   
      • The domain name of your locked tenant    
      • Any error messages you are receiving.   
      • Details about the authentication issues you are experiencing.   
      • Confirmation that you are the administrator of the locked tenant.   
    7. Submit your ticket: Follow the prompts to submit your support request. You will likely receive a ticket number for tracking.   

    When you open a support ticket, please make sure to turn off the Support Assistant (AI) in the help panel.  

    Several customers have reported issues when the Support Assistant is turned on  the system sometimes fails to display the “Contact Support” option.  

    As shown in the screenshot, simply switch Support Assistant > Off, then type your issue description.  Once the AI is off, the “Contact Support” button will appear normally, allowing you to submit a ticket directly.

    Important notes:    

    • This new trial tenant will not give you access to any of the data or settings in your original locked tenant. It is solely a temporary means to contact Microsoft support.   
    • Be prepared for Microsoft support to ask for verification of your identity and administrative rights for the locked tenant.   
    • The resolution time might be longer as you are contacting support from a different tenant.   
    • Remember to cancel the trial subscription for the new tenant once your issue with the original account is resolved to avoid any unintended charges. You can typically do this within the Microsoft 365 Admin Center under "Billing" -> "Your products."   

    I hope these steps will help resolve your issue. If you need further assistance, we are always here to help.     

    Thank you again for your time and understanding. While my initial response may not resolve the issue immediately, I’d like to gather more details about your situation so I can assist you more effectively.    

    I really appreciate your patience, and I’m here to help. Looking forward to your response.

    Because the old phone is no longer available, the MFA methods for the admin account must be reset by an administrator or, if this is the only admin, through Microsoft support.

    Follow the path that matches the situation:

    1. If there is another admin in the tenant

    Ask another Global/Authentication Administrator in the tenant to reset MFA for the affected admin account:

    1. The other admin signs in to the Microsoft Entra admin center: https://entra.microsoft.com.
    2. Go to Entra ID > Users > All users.
    3. Select the affected admin account (for example, ******@40srp7.onmicrosoft.com).
    4. Open Authentication methods.
    5. Select Require re-register MFA.

    After this, the next time the admin signs in, the old MFA methods (phone numbers, Authenticator registrations, etc.) are removed and the portal will prompt to set up new MFA methods (new phone number, new Microsoft Authenticator app, etc.).

    1. If this admin is the only administrator in the tenant

    If there is no other admin who can perform the reset, the MFA reset must be done by Microsoft’s Data Protection team via a support case:

    1. Call Microsoft’s global customer service phone number for the region (see Customer service phone numbers - Microsoft Support in the context articles).
    2. When connected, clearly state:
      • The issue is loss of access to Microsoft Authenticator / MFA for the only Global Administrator.
      • A request is needed for the Data Protection team to reset the admin’s MFA.
    3. Follow their identity verification process. Once verified, they can reset the MFA settings so that a fresh sign-in and MFA registration can be completed.
    4. If the admin can still sign in and reach Security info

    If password sign-in still works and the account can reach the security info page, MFA methods can be updated directly:

    1. Go to the Security info page: https://aka.ms/mysecurityinfo (or https://aka.ms/security-info as referenced).
    2. Delete the old phone / Authenticator methods that are no longer usable.
    3. Use Add sign-in method to add a new Phone and/or set up the Microsoft Authenticator app on the new device, following the prompts.

    If none of these options are possible (no other admin, cannot reach Security info, and cannot open the admin portal), contacting Microsoft support and asking for the Data Protection team is required to regain access.
