Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Good day Kirton,
Might I confirm whether you are the "only Global Administrator" of this tenant?
- If not, please follow "Step 1".
- If you are the Global Administrator, please follow "Steps 2 and 3" to contact the Data Protection Team so they can verify your information and assist you in regaining access to your account.
1/ Reset MFA methods
If you still can sign in to your administrator account in your browser or you tenant has another global admin, please try to reset the MFA methods. Once reset, we recommend re-registering MFA using the Microsoft Authenticator app instead of SMS.
In the Entra admin center, an administrator can set user accounts to require a re-enrollment of multi-factor authentication (MFA). Ask your administrator to follow the steps shown in the following article:
Manage user authentication methods for Microsoft Entra multi-factor authentication
- Sign in to Microsoft Entra - Microsoft Entra admin center
- User -> all users. Select the user you want to act on, and then select "Authentication methods". then select "Require multi-factor authentication re-registration".
2/ Contacting Microsoft Data Protection team by phone support
In this situation, the Microsoft Data Protection team has tools and processes in place to verify identity and regain access to administrator accounts.
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
If you can use English, you may prefer these numbers:
(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 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.
Please try "2 or 3"times until you can reach out to an agent.
2/ Another work around
If you still cannot reach to agent, there is still a workaround, you might consider registering for a new tenant by signing up for a trial subscription. This would allow you to create a new tenant following the prompts provided. 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.
