Based on other users' experience. If the ticket has already been escalated to the data protection team, it may take a few weeks to be resolved.

As u dont have access to the app anymore, the only way to resolve this is to request for Product Support to reset MFA for the affected user for microsoft accounts. Contact Product Support with the email address for the affected user. https://azure.microsoft.com/en-us/support/create-ticket

See: https://learn.microsoft.com/en-us/xandr/curate/troubleshooting-multi-factor-authentication-mfa?source=recommendations#dont-delete-mfa-app

But since you already created a ticket, I will recommend you use the Global Support numbers:

If you're unable to log in with the only Global Admin account due to a lost phone and MFA without backup, and there are no other admin users, your options are:

1. Contact Microsoft Support directly via their emergency support channels or escalate the ticket by calling the support hotline.
2. Use the Azure AD account recovery if any recovery methods were set up, like alternative email or phone.
3. Register a new Global Admin using the billing account owner’s privileges if possible.

Keep pushing the support ticket for an urgent resolution.

Thank you for posting this in Microsoft Q&A.

As I understand you are unable to access Azure using Global admin account as you have lost the phone on which Microsoft authenticator app is configured.

In this situation you have only one option to recover the Global Admin account.

If you are the only global admin on the account and are blocked entirely, you can reach out to our support team. You can look into below article to get support numbers depending on your country.

https://support.microsoft.com/en-us/topic/global-customer-service-phone-numbers-c0389ade-5640-e588-8b0e-28de8afeb3f2

or creating a ticket through a different account:  https://learn.microsoft.com/en-us/microsoft-365/admin/get-help-support?view=o365-worldwide#phone-support

Create a ticket with Microsoft support team. Give them the tenant ID which is locked out in your description. Tell them that no admin account has access anymore and your partners also have no access anymore.

Once you create a ticket with support team you will have to work with our data protection team. You will have to first prove your identity against your tenant for security purpose. Post that this team will help you with help you in getting access to your tenant or unlock your account depending on your scenario.

Also, for the future, you can create an emergency access account (break glass) in Azure AD. This account will help prevent being accidentally locked out of your Azure Active Directory (Azure AD) organization because you can't sign in for any reason.
