Hello Microsoft Support Team,

I am the owner of a Microsoft 365 Business organization purchased directly from Microsoft.

I am currently unable to access my organization's administrator account.

Situation:

  • I know the correct password for my original administrator account.
  • My account uses an @onmicrosoft.com address.
  • Microsoft requires Microsoft Authenticator approval or a verification code.
  • I have NEVER registered Microsoft Authenticator for this account.
  • No alternative authentication methods are available.
  • My other users have standard permissions and cannot access the Admin Center.
  • I have already tried contacting Microsoft Support by phone, but the call was transferred to an agent queue and nobody answered.

Organization details:

  • Custom domain: pontobase.pt
  • Subscription: Microsoft 365 Business, purchased directly from Microsoft.

I need assistance recovering access to my existing tenant.

Could a Microsoft Support Moderator please contact me privately and help initiate a Data Protection / Tenant Recovery case?

I can provide proof of domain ownership, subscription details and company documentation.

I do not want to create a new tenant. I need to recover my existing organization.

Thank you for your help.

    Dear Maria,

    if you're the only Global admin, you will need to contact Data Protection team. They can help you regain access to your tenant.

    Please note that this forum is not Microsoft support, this is a user-to-user support forum. Therefore, I cannot directly escalate this for you. However, I can guide you how to contact Data Protection team.

    First, you can try phone support with the script below, preferably during local business hours. it will help you get past the initial AI system to reach the live support team.

    If it's not working, please follow this link to create a trial tenant: https://www.microsoft.com/microsoft-365/business/microsoft-365-business-basic?msockid=3eb6980b5c6860e63a588d0c5d1761d6 - after that you will be able to access to Microsoft 365 Admin Center to raise the ticket

    Assuming that you have already created an account after registering a free trial and you can go to Microsoft 365 admin center and click "Help & support" icon to raise your ticket.   

    Please have your original tenant ID, domain, administrator account, subscription/billing information, and an alternate contact email and phone number available. Only provide sensitive information privately through the official support case.

    Important note: if you do create the trial and it resolves the issue, please remember to cancel the subscription afterward to avoid any related charges.
