Unable to access Microsoft 365 Developer Program tenant due to lost MFA device

Question

I am locked out of my Microsoft 365 Developer Program tenant because I no longer have access to my Microsoft Authenticator app.

I am the only Global Administrator for this tenant. I recently changed to a new phone, and my old phone was factory reset. The only MFA method configured for my administrator account was Microsoft Authenticator on the old device.

I know my administrator username and password, and I still have access to the personal Microsoft account that I used to register for the Microsoft 365 Developer Program. However, I cannot complete the MFA verification because the registered Authenticator device is no longer available. There are no other Global Administrators who can reset my authentication methods.

I have already attempted the available self-service recovery options, but none are available.

I kindly request assistance with resetting my MFA registration or restoring administrative access to my Microsoft 365 Developer Program tenant. Please let me know what information or verification is required to confirm ownership.

Thank you.

Update:

Thank you for your response.

I wanted to provide an update on everything I have tried so far.

• I contacted Microsoft Support and a support case was created (Case #****[Moderator note: personal info removed]).

I was advised to contact the Microsoft Data Protection team by phone. I called Microsoft Support and waited in the Data Protection queue for over 4 hours, but I was never connected to a Data Protection agent.

I was also advised to create a Microsoft 365 Business trial tenant and raise a support request on behalf of my affected tenant. Unfortunately, I was unable to use that process for my Microsoft 365 Developer Program tenant.

I still had access to the personal Microsoft account that I used to enroll in the Microsoft 365 Developer Program, but I could not access the Global Administrator account because the only MFA method (Microsoft Authenticator) was registered on my old phone, which had been factory reset.

There were no other Global Administrators available to reset my authentication methods.

Since I was unable to recover access through any of the available support channels, I decided to delete my Microsoft 365 Developer Program profile.

Within approximately 5 minutes, I rejoined the Microsoft 365 Developer Program using the same personal Microsoft account. However, instead of receiving a new developer subscription, my dashboard now shows my previous tenant ([Moderator note: personal info removed]) as inactive/expired with 0/0 days remaining, and it states that the subscription will be deleted if it is not used.

Could you please clarify the following?

Is my original tenant ([Moderator note: personal info removed]) still recoverable, or is it permanently inactive?

Why was a new developer sandbox not provisioned after I rejoined the Developer Program?

Do I need to wait before I am eligible to receive a new Microsoft 365 Developer Program subscription, or is there another step that I need to complete?

Is there any way to reactivate my Developer Program subscription or provision a new sandbox?

Thank you for your time and assistance. I appreciate any guidance you can provide.Update:

Hi @Abhishek Yadav

In this situation, there are two official paths you can take to regain access to the tenant:

1.Please visit the following page and reach out to phone number via: Customer service phone numbers - Microsoft Support

From what I know, you will need to get past the initial AI system to reach the live support team. You can refer to the guide below for tips on how to get through more easily:

2.If method 1 is not working, please follow this link to create a trial tenant: https://www.microsoft.com/en-us/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. The agent will be able to create a ticket for you under the affected tenant and then transfer this ticket to Data Protection team who could help you to regain access.     

Please mention that you are raising ticket on behalf of the affected tenant that you do not have access to. The support team will help you to create ticket on the affected tenant then later on the Microsoft Data Protection team will assist you.

Note: This process will take more time than usual (7-14 working days) for your account to get access again as Data Protection is always overwhelmed with the number of tickets. As I am forum moderator, I do not have access to Microsoft internal system to assist or push this process to be quicker.

On the other hand, if you do create the trial and it resolves the issue, please remember to cancel the subscription afterward to avoid any related charges. 

I hope my information is helpful. Please give me any updates once you get this resolved.
