Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi Yahya AlZeir
Since this is a Microsoft 365 Business account and you’re currently unable to sign in even with the admin account, if there is another Global Administrator in your organization who can still access the Microsoft 365 admin center, you can ask them to follow this article to proceed to reset your 2FA so that you could re-register again: Manage authentication methods for Microsoft Entra multifactor authentication - Microsoft Entra ID |…
If you are the only administrator, or no administrator is currently able to sign in, you’ll need to contact Microsoft Support for help recovering access to the tenant. They may need to verify your organization/tenant ownership before assisting with the admin account recovery. You might need to contact Microsoft support team via phone service number: Customer service phone numbers - Microsoft Support. 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.
In case the phone line is not supportive, you can consider directly submitting a support request via trial tenant as a helpful workaround:
-Create a temporary Microsoft 365 tenant using a trial license: Go to Microsoft 365 Business Plans and Pricing and click Try for free to set up a temporary Microsoft 365 tenant with a trial license.
-Use this new account to sign in to the Microsoft 365 Admin Center and submit a support request on behalf of your primary (locked) account.
-Select the Help & support (headset) icon. If Support Assistant is enabled, turn it off > Type contact support in the search box > Select Contact support, then choose Phone or Email to submit your request.
Note: This method doesn't require you to use your new account for your business. Instead, it allows you to create a temporary global administrator account so you can submit a support request, as your original global administrator account is locked out due to issues with multi-factor authentication. The trial account is free for one month. Be sure to delete it after submitting your support request to avoid any automatic renewals or charges from Microsoft.
For further instructions, you can follow this guide: Get support - Microsoft 365 admin | Microsoft Learn.
Once access has been restored, you can then reset the affected passwords and review the accounts for any unexpected changes, such as mailbox forwarding or inbox rules.

Therefore, please kindly contact the Microsoft Support team for the most efficient help.
I hope this information helps.
