Hi, I'm John! I will help you with this.
If you are the only Global Admin, then the only way forward is to contact Microsoft 365 Business support directly via phone https://support.microsoft.com/topic/customer-service-phone-numbers-c0389ade-5640-e588-8b0e-28de8afeb3f2 They’ll ask you to verify your domain ownership and can help reset the MFA requirement so you can get back into your account.
Or, you can create a temporary trial Microsoft 365 Business account and use it to reach Microsoft Support directly through the admin center, that often helps you connect with the right support team faster:
- Create a trial account here: https://www.microsoft.com/microsoft-365/business/microsoft-365-business-standard-one-month-trial
- Using the trial account, Sign in to Microsoft 365 admin center https://admin.microsoft.com
- Select Support > Help and support, enter your question and select Contact support.
- Mention your support case number.
- You may cancel your trial subscription before the free trial period ends to stop future charges.
I really hope this information is helpful! Let me know if you have any further questions or concerns.
Regards,
John J.D.
