If you are the sole global admin and have been locked out of your Microsoft 365 account due to multifactor authentication (MFA) issues, you will need to contact the Azure Data Protection team for assistance. Since you have already opened a support ticket, it is crucial to follow up with them directly if you have not received a response. You can contact the Azure Data Protection team at +1 866-807-5850 for immediate assistance. They can help you reset your credentials and regain access to your account.
Additionally, to prevent future lockouts, consider setting up an emergency access account (also known as a break-glass account) in Microsoft Entra, which can help you avoid being locked out in similar situations in the future.
