Users cannot log in to Zivver in Outlook with ADFS single sign-on (SSO).

The user is not automatically logged in to Zivver in Outlook. If the user logs in manually, they receive a 2FA challenge on their Windows workstation. This also happens with both Windows and Kerberos exemptions in the Zivver admin panel.

Cause

Windows Authentication is not enabled under Intranet.

To diagnose the issue, follow these steps:

1. Go to ADFS Management Console > Service > Authentication Methods.
2. Under Primary Authentication Methods, click Edit.

Warning

Perform an impact analysis before implementing a solution.

Solution 1

Add WIASupportedUserAgent as an ADFS property. This enables logins using Windows Authentication. By default, this option is enabled.

Solution 2

Consider enabling Windows Authentication in the ADFS Management Console.
