Unable to connect with the tenant administrator account

Hello,

I manage the Office365 tenant of a non profit organization. MFA was activated by another person on the general administrator account. This person no longer has access to the Microsoft authentication application, nor to the phone number used to receive confirmation codes by SMS.

We do not have a second account with administrative rights.

In short, I cannot log in with administrative rights. How can I recover the rights?

Thank you in advance for your help.

    Hi,

    I'm sorry to hear you're having trouble accessing your admin account. Here's how we can get you back in control:

    1. Contact Microsoft Support for Account Recovery

    Since you can't access the MFA methods and there's no other admin account, you'll need to reach out to Microsoft Support to help regain access.

    1. Find the support number:
    2. Explain the situation:
      • Let them know you're the administrator of your organization's Microsoft 365 tenant.
      • Explain that MFA was set up by someone who no longer has access to the authentication methods.
      • Mention that you don't have another admin account.
    3. They will guide you
      Microsoft Support will verify your identity and ownership of the tenant. Be prepared to provide any necessary information, like domain ownership proofs or organization details.
    4. Prepare for verification
      • Access to domain registrar: Ensure you have access to your domain's DNS settings. Microsoft might ask you to add a TXT record to verify ownership.
      • Organization details: Have any relevant documents or information about your non-profit association ready.
      • Setup additional admin accounts (After regaining access) Create another Global Admin Account: Once you're back in, create at least one more admin account to prevent this situation in the future. Setup Alternative MFA Methods: Add backup authentication methods to your admin accounts, like alternative phone numbers or emails. Consider a Break-Glass Account: This is an account with admin rights that's used only in emergencies and is secured separately.

    Important Notes:

    • Stay Patient: The recovery process might take some time to ensure security.
    • Avoid This in the Future: Always have more than one admin and multiple MFA options.

    I hope this helps you get back into your admin account. If you have any more questions or need further assistance, feel free to ask.

    Best regards,
    T.
