AADSTS90072: User account ' from identity provider 'live.com' does not exist in tenant 'Microsoft Services' and cannot access the application '0000000c-0000-0000-c000-000000000000'(Microsoft App Access Panel) in that tenant. The account needs to be added as an external user in the tenant first. Sign out and sign in again with a different Azure Active Directory user account

Hi @Krunal Hinduja

The error code AADSTS90072 is due to the external account that the user signs in with doesn't exist on the tenant that they signed into; so the user can't satisfy the MFA requirements for the tenant. The account must be added as an external user in the tenant first. Sign out and sign in with a different Microsoft Entra user account.

To resolve the issue, check if the user account exists in Azure AD Tenant. If the user doesn’t exist in the tenant, add them to your Azure AD. If the user is present, check if the invitation is accepted; If not, ask the user to accept the invitation.

Hi @Krunal Hinduja

If you backed up previous validator information to the cloud, please refer to this document:

Back up and recover account credentials in the Authenticator app

If you don't have a backup,you can fill out the Microsoft Account Recovery form to prove that you are the owner of the account. I know it's a somewhat arduous process, but these steps are taken as security measures, and you can recover the account that way. https://support.microsoft.com/en-us/account-billing/help-with-the-microsoft-account-recovery-form-b19c02d1-a782-dee6-93c3-dc8113b20c42

If you have other recovery options set up and can access https://myapps.microsoft.com/ , you can re-add the authenticator (and other authentication methods) on that page.

Meanwhile, if the reply is helpful to you, please try to mark it as an answer to help others who encounter the same issue and read this thread. Thank you for your understanding and patience!
