Hi Joy,
Thank you for taking the time to share detailed information about your situation and I’m sorry to hear that you’ve been locked out of your Microsoft 365 Admin account.
Since you are the only administrator of your tenant and you’re currently unable to sign in, the next essential step is to involve the Microsoft Data Protection team, as they are the only team authorized to help recover an admin account in these circumstances.
Since you mentioned that you have tried for days contact Microsoft Support, I assume that you have tried the primary phone support method but you cannot reach a live agent. In this case, there is still a workaround that you might consider registering for a new tenant by signing up for a trial subscription. 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 set up a new tenant, please follow these steps:
- Visit Microsoft 365 Business Plans and Pricing | Microsoft 365. This would allow you to create a new tenant following the prompts provided.
- Follow the guided setup process to create a new account for a new tenant.
- Once your tenant is created, you should be able to access the support portal and submit your ticket referencing your locked account without further issues.
- To create a Support ticket: sign into Microsoft 365 Admin Center > Support > 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 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."
Please remember to cancel the trial subscription after your issue is resolved, as this will help you avoid any accidental billing. You may prefer the following resource for detailed instructions: Cancel your Microsoft business subscription in the Microsoft 365 admin center | Microsoft Learn
Hope this helps you regain access to your account quickly. Should you have any further questions or need additional assistance, please feel free to share them in the comment below. I'm very happy to help.
