I am the only Global Administrator of tenant <Mod mask PII> xxx.onmicrosoft.com (Tenant ID: <Mod remove PII> ).

The original account <Mod mask PII> @xxx.onmicrosoft.com

was renamed to <Mod mask PII> @ovahq.co.in

My mobile device with Microsoft Authenticator was lost and no alternate MFA method was configured.

I have full control of the domain ovahq.co.in and can verify ownership by adding a TXT record in DNS (GoDaddy).

Please understand that as forum moderators, we do not have the tools or sufficient access to make changes to user accounts, including logging in, resetting passwords, or modifying access rights. For your security, only Microsoft Support can assist with these requests. 

Hello @Sivanagalakshmi Polam,

Thank you for your detailed explanation, and I’m really sorry to hear how much time and effort you’ve already spent trying to recover access to your admin account. I fully understand how frustrating it is to be stuck in the automated support loop.

If you are the only admin, you will need to contact Microsoft’s Data Protection team. This team has the authority and the specific security procedures to verify your identity as the legitimate owner of the account and then reset your MFA settings from their end. Please try to find the related hotline number to call the frontline and let them raise a ticket for you: Customer service phone numbers - Microsoft Support    

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 you may initially interact with an automated system, so here is an example of how you can answer the prompts to reach the right team more quickly:  

• 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 call, you will be asked to provide information that verifies your identity and proves ownership of the tenant, such as your organization name, billing information, contact email, phone number, or other subscription‑related details. This is a normal part of the security procedure.

If you are unable to reach a support agent by phone, there is a workaround you might consider: You can register for a new Microsoft 365 tenant by signing up for a trial subscription here: Microsoft 365 Business Plans and Pricing | Microsoft 365    

Once the new tenant is created, you can access the admin center and submit a support ticket from there, requesting to speak with the Data Protection Team on behalf of your original tenant.    

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.    
• 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.   I hope the information provided helps guide you in the right direction. Although I’m unable to take direct action on your account as a forum moderator, I sincerely hope that the steps and recommendations I’ve shared can support you through the process.  

  

Warm regards,

Answer 2

To regain access to your Global Administrator account after losing your mobile device with Microsoft Authenticator and without an alternate MFA method, you will need to contact Microsoft Support directly. Since you are the only Global Administrator, you may face challenges in resetting your MFA settings without assistance.

Here are the steps you can take:

1. Contact Microsoft Data Protection Support: Reach out to Microsoft Global Customer Service by phone. Explain your situation, including that you are the sole administrator and have lost access to your MFA method. You can request a temporary MFA reset during this call.
2. Verify Domain Ownership: Since you mentioned you can verify ownership of the domain by adding a TXT record in DNS, be prepared to provide this information to support, as it may help in verifying your identity.
3. Alternative Method: If you cannot reach a live agent, consider creating a temporary account (trial tenant) to submit a support ticket on behalf of your original tenant, as outlined in the context.

It's crucial to communicate clearly that you are locked out due to the loss of your authenticator and that you need immediate assistance to restore access to your account.
