A free program from Microsoft that provides developers with the tools, resources, and sandbox environments needed to build solutions for Microsoft 365.
Hi,
If your account is also an admin account and there are no other available global administrators in your tenant, then the only way to regain access is contact Microsoft support. Please try locating the appropriate hotline for your region here: Customer service phone numbers - Microsoft Support
In this situation, the Microsoft Data Protection team has tools and processes in place to verify identity and regain access to administrator accounts.
During the phone call, you will need to provide the information associated with your subscription, such as your company name, billing details, phone number, and an alternate email address, etc. This information allows the Data Protection team to verify your identity and securely assist you in regaining access to your administrator account.
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.
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. 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.
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.
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."
Ticket Support: In the Microsoft 365 Admin Center > Support > Help & Support.
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
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.
