Error AADSTS50058 using external accounts in Azure AD tenant

    Question

  • Hi there,

    We have an Angular frontend wich connects to an ASP.NET Core backend. The backend connects to 'external' services (the services are not in the same application, but are managed by us) by getting a token for the currently logged in user. Since yesterday the app is having issues (without us deploying anything in the past weeks), and it throws error AADSTS50058 on the backend.

    Our Azure AD tenant (<something>.onmicrosoft.com) has both internal and external accounts. Some people have been added with an external email address and authenticate themselves on the login page of the respective service. These accounts are experiencing these issues. The users of internal accounts (<someone>@<something>.onmicrosoft.com) do not experience these issues.

    Timeline

    Yesterday our application in the EU region failed, but the US one was still working. Today, the application in the US region is also broken.

    Issue occured (and solved) earlier

    As you can see in this forum post, the issue occured earlier. And it was solved earlier, too.

    Kind regards, Rick

  • @Rick and Sadiqh - There has been a fix that has been rolled out for this issue. Suggest you to authenticate the external users and re-check.
