SharePoint Online External users redirected to ADFS sign-in page RRS feed

  • Question

  • Some of our external users are experiencing weird behavior when trying to sign-in. Login flow is "User browse the site url --> enter their external signin address --> Choose 'Microsoft Account' as the account type --> Enter their password --> They get redirected to organizations ADFS sign-on page --> user enter their password and keep getting the wrong userid or password message.


    I have checked in AAD portal and user is added as a 'Guest'. However, I can't understand why user is getting redirected to ADFS SSO page. As an external user with Microsoft account, user should authenticate with Microsoft Live ID, not with ADFS.

  • Hi,

    I can't reproduce this issue in my environment.

    Which browser did you use?

    I suggest you clear the browser cache. 

    After that, check if it works fine.

    Best Regards,

    Carl Zhou

  • Hi, i also have this issue. What was the solution? This seems to work for some domains but not for any external users from a specific domain. Why would that be? The tenant is not configured to restrict domains at all, and they are using an outside internet connection. They are not connected to our network. Why would they be redirected to our ADFS server to authenticate? When i use other test external accounts such as gmail accounts or my own account from another separate tenant, it behaves correctly, and sends a unique code to the email address which can be used to log in.

    The browser used isn't really relevant; it happens to all users from this external domain.
