Locked out of Microsoft 365 admin account due to MFA after changing device. Domain owner with DNS access.

Jeremy Prommenschenckel Gazquez 0

Hello,

I am currently locked out of my Microsoft 365 tenant because of multi factor authentication after changing my mobile device. I no longer have access to the authenticator app and I do not have any backup authentication methods configured.

I know the username and password of my business account and can log in up to the MFA step, but I cannot complete the verification because the authenticator is linked to my old device.

I am the global administrator and the owner of the domain. I still have full access to my domain DNS through my provider and I can verify ownership if needed.

The issue is that Microsoft support is sending me in a continuous loop. The chatbot tells me that I need to request a phone call. However, when I request the call, it gets cancelled or I am redirected again to the website without being able to speak to a real support agent. It seems that it is only possible to get help through automated online channels.

I have already been through this loop three times and currently have two open cases with the chatbot, but the issue remains unresolved. I have spent several hours trying to fix this without success.

My email account is part of a Microsoft 365 business tenant, not a personal Microsoft account. The account recovery form for personal accounts does not recognize my email.

I urgently need to know the fastest way to escalate this case or recover admin access.

Has anyone experienced a similar situation? What is the correct process to recover access as a global admin when MFA is lost but domain and DNS ownership can be verified?

Any guidance would be greatly appreciated.

Thank you.

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 @Jeremy Prommenschenckel Gazquez,

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, especially when you urgently need to regain control of your tenant.

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

I know you mentioned that you have already attempted calling multiple times without success, but I would kindly ask you to try once more using the tips below. These steps may help you bypass the automated loop and reach an agent who can escalate your case correctly.

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, after trying again, you still cannot reach the Data Protection Team, 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,
