Microsoft Authenticator can't working after changed primary email address in bussiness account

Question

I changed my email address from onmicrosoft.com account to primary domain. After that I cannot use the Microsoft authenticator to authenticate and log in to my global admin account.

Please help me to resolve this problem.

If you are the only global admin on the account and are blocked entirely, you can reach out to the Azure / 365 Data Protection team to restore access. 866-807-5850

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. https://docs.microsoft.com/en-us/azure/active-directory/roles/security-emergency-access
