Answer 1

Dear @Brad Schultz,

Thank you for reaching out to Microsoft Q&A forum.

I'm truly sorry to hear about the difficulties you're experiencing with accessing your Microsoft 365 business account. Losing control of the Global Administrator account for your business’s Microsoft 365 environment is a serious issue.

While I can provide the steps and the official terminology you need, please understand that recovering a Global Administrator account without any known credentials or access to recovery methods cannot be resolved by a forum moderator. This is a security-critical issue that requires direct interaction with Microsoft's Data Protection Team to prove ownership of the entire organization. 

First, does your tenant have another global admin account, or is this the only one? If there is another global admin account, please ask the owner of that account to try revoking or resetting MFA for your account. 

Unfortunately, if you are the sole admin of your organization, you cannot resolve this on your own. 

The best way to do this for a business account is by phone. You can follow this article to check global customer support phone number from your region.

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

In some countries, it is an automated conversation like: First, when you call the hotline, it will be asked as follows:  

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 the other administrator in your organization?  

You: No.  

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

You: Yes  

Alternative, you can create a new tenant account and submit your request from there.   

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

1. Visit Compare Office 365 Enterprise plans and pricing, choose any plan and click try for free to start a free trial.   
2. Choose any plan (e.g., Business Basic, Standard, or Premium) and click "Try for free" to start a free trial.  
3. Follow the guided setup process to create your new trial account.  
4. Once the new tenant is created, you should be able to access its support portal and submit your ticket.  
5. Log in to the Microsoft 365 admin center (admin.microsoft.com).  
6. Navigate to Show all > Support > New service request  
7. In the request, explain your situation in detail.  

The support team will guide you through the identity verification process to help you regain access to your account.  

Important notes:  

• This new trial tenant does not grant you access to data or settings of your original locked tenant. It only serves as a temporary way to contact Microsoft support.  
• Be prepared for Microsoft to want to verify your identity and administrator privileges for the old tenant.  
• The processing time may be longer because you are contacting support from another tenant.  
• Remember to cancel the trial subscription as soon as your original account is restored to avoid unwanted charges. You can do this in the Microsoft 365 admin center under Billing > Your products.  

I truly hope you get your issue resolved swiftly. Please know that even though I can't directly intervene, directing you to the correct, specialized support is the most effective help I can provide from my position. If you need further assistance, don’t hesitate to reach out again. Have a wonderful day.

Answer 2

If you are a Microsoft 365 Global Administrator and are locked out of your account due to issues with two-factor authentication (2FA), it is possible that your account may be temporarily blocked after too many failed login attempts. To regain access, you will need to contact Microsoft support directly, as you may not be able to resolve this through the usual help files.

Here are some steps you can take to contact support:

1. Contact Microsoft Data Protection Support by Phone: You can reach out to the Global Customer Service phone number to raise a request for resetting your authentication method. Make sure to explain that you are the only admin and have lost access to your account.
2. Use the Admin Center: If you can access the admin center, you can select Help & support at the bottom right of the page, type your issue, and then select Contact Support to get in touch with a support agent.
3. Create a Temporary Account: If you cannot reach a live agent, consider signing up for a trial subscription to create a new tenant. This will allow you to access the admin console of the new tenant and submit a support ticket requesting help for your original tenant.

These methods should help you regain access to your account and resolve the 2FA issues you are experiencing.
