Account Cannot Add or Manager Users

Question

My client's account is getting this error message when trying to log in or visiting the User Management page in our Azure Portal:

{ "sessionId": "ad1fe44c76ef485f9ceb2bf55c9952b3", "errors": [ { "errorMessage": "interaction_required: AADSTS16000: User account '{EUII Hidden}' from identity provider 'live.com' does not exist in tenant 'Microsoft Services' and cannot access the application 'f9885e6e-6f74-46b3-b595-350157a27541'(Microsoft_AAD_UsersAndTenants) 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. Trace ID: d18af949-0a5a-4479-8a02-29516eb70000 Correlation ID: a73afa50-0e37-423e-92aa-b83c7e58c994 Timestamp: 2025-11-11 17:38:38Z", "clientId": "f9885e6e-6f74-46b3-b595-350157a27541", "scopes": [ "74658136-14ec-4630-ad9b-26e160ff0fc6/.default" ] } ] }

He is requested to login again and after attempting to gets the error below which seems to say he's not a Tenant of his own account?

We are trying to invite other members (myself) of the development team to manage and access my client's Azure BizSpark portal so we can use resources for an app we are building from his account. We have already created an Azure DevOps org and project with no issues there.

Thanks!

The error message indicates that the user account from the identity provider 'live.com' does not exist in the specified tenant ('Microsoft Services'). This typically means that the account needs to be added as an external user in the tenant before it can access the application.

To resolve this issue, you should:

1. Invite the user: Ensure that the user account you are trying to add is invited to the Azure tenant. You can follow the steps in the Azure portal to invite guest users.
2. Sign out and sign in again: After inviting the user, instruct them to sign out and then sign in again with the correct Azure Active Directory user account.
3. Check the account type: Make sure that the account being used is the correct type (i.e., it should be an Azure Active Directory account rather than a personal Microsoft account).

If the user continues to experience issues, you may need to verify that the account has been properly added and that the necessary permissions are granted for managing users in the Azure portal.
