Answer 1

Hi @Ahmed Abozead,

Thank you for your message regarding the problem you are experiencing with accessing your admin account.

Based on your description, it appears that the sign‑in issue may be occurring at the security verification (multi‑factor authentication). Although the password is accepted, the system is requesting an SMS verification code that does not arrive, which can sometimes happen if the phone‑based authentication method is not functioning as expected. As a result, the sign‑in process cannot be completed, which is why access to the account is currently not possible.

Since you are the sole Global Administrator for the tenant, please follow the options below to complete the account recovery process and regain access.

---

Option 1: Contact Microsoft Data Protection Support by phone (Please proceed with the second option if contacting phone support is not applicable to the situation)

To regain access to your admin account as you can't access the Admin Portal, you can try reaching out to the Global Customer Service phone to raise a request for resetting your authentication method here: Customer service phone numbers - Microsoft Support. During the call, request to speak to an agent, and share with them every detail related to your query and also mention that you are the only admin lost access to your account. This should allow you to contact the appropriate team so you can solve this incident as soon as possible.

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:

IVR: What kind of problem are you concerned about?

You: Authentication.

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 another administrator in your organization?

You: No.

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

You: Yes. I need to create a ticket. Please send me directly to the Data Protection Team.

Option 2: Create a new tenant to submit a support ticket (Alternative method)

If you cannot reach a live agent, there is still a workaround, you might consider registering for a new tenant by signing up for a trial subscription via this link Microsoft 365 Business Plans and Pricing | Microsoft 365 (please select "Try for free" under a business subscription).

When prompted, enter your email. You can use your personal email or create a new Microsoft personal account for this step. Then select Set up account to move forward.

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.

To create a support ticket: In the Microsoft 365 admin center > Help & Support.

In your ticket description, you'll need to clearly explain that you're trying to regain access to your previous Microsoft 365 tenant and need help from the Data Protection team. Here's a message you can use or adapt:

"Hello, I’m currently unable to access my previous Microsoft 365 tenant due to losing MFA access, which prevents me from receiving verification codes. I’m the only global admin, but I’m locked out and unable to generate a QR code or bypass MFA.

I created this new tenant solely to request assistance. I kindly ask to be connected with the Data Protection team to verify my identity and help me recover access to the original tenant.

This is urgent, as I rely on Microsoft 365 for my work and have been unable to operate for several days. I’m available to provide any documentation or verification needed to support the recovery process."

It is important to note: Please remember to cancel the trial subscription once your issue is resolved to avoid any unintended charges. You may prefer the following resource for detailed instructions: Cancel your Microsoft business subscription in the Microsoft 365 admin center | Microsoft Learn.

I hope this helps you regain access to your account quickly. I'm glad to assist and truly hope the information provided has been useful. Please feel free to reach out anytime if you need further assistance.

Answer 2

Because this is the only admin account and SMS-based MFA is failing, the issue cannot be fixed by self-service alone and must be handled by Microsoft support (Data Protection team).

Use these steps:

1. First confirm basic troubleshooting
   • Try signing in and triggering the SMS code from:
     • A different browser or InPrivate/Incognito window.
     • A different device and/or network (for example, mobile hotspot instead of office Wi‑Fi).
   • If the SMS still never arrives and you cannot complete MFA, proceed to step 2.
2. If there is any other Global Administrator
   • Have that admin sign in to the Microsoft 365/Azure portal.
   • In Microsoft Entra ID, go to Users → select the affected admin account → Authentication methods → choose Require re-register multifactor authentication.
   • Next time the affected admin signs in, MFA registration will be reset and a new method (such as a working phone number or Microsoft Authenticator) can be configured.
3. If this is truly the only admin account (no other Global Admins)
   • This is a tenant lockout scenario. Microsoft’s Data Protection team must verify identity and reset the admin’s MFA from the backend.
   • Call Microsoft’s global customer service phone number listed under Customer service phone numbers - Microsoft Support.
   • When the IVR asks what the problem is, clearly indicate:
     • The issue is with Authenticator / MFA / verification code.
     • The product is Office 365 for business / Microsoft 365 for business.
     • The account is a company (work) account.
     • Confirm being an administrator and that there is no other administrator.
     • Ask to create a service request and be routed to the Data Protection team (or Tenant Recovery) to reset the admin MFA.
   • Be ready to provide:
     • The admin username (work email).
     • The tenant domain.
     • Error messages seen when trying to receive the SMS.
     • Confirmation that this is the only admin and that you know the password but cannot pass MFA.
4. Alternative if phone support is hard to reach
   • Create a temporary, separate Microsoft 365 trial tenant (for example, from the Microsoft 365 Business or Enterprise trial page).
   • In that new tenant, go to the Microsoft 365 admin center → Support → Help & support and open a ticket.
   • In the ticket, clearly state that the problem is with a different, existing tenant where you are the only Global Admin and are locked out due to MFA/SMS not working, and request escalation to the Data Protection team to reset MFA on the original tenant.
   • This trial tenant is only a channel to contact support; it does not give access to the locked tenant’s data.

Once Microsoft verifies identity, they can clear or reset the MFA methods on the admin account so that sign-in works again and a new, reliable MFA method (such as Microsoft Authenticator plus backup phone/email) can be configured.
