Couple of questions:
1. Is this affecting only one or two users?
2. Is the error a QuickHelp error or an ADFS error? NOTE: The best way to verify is by checking the URL of the error.
If it's a QuickHelp error, please enter a support ticket by clicking here or emailing firstname.lastname@example.org. Please remember to reference the error/incident ID.
If it's an ADFS error, please send the incident ID to your IT/Identity team. You can also try logging in to your ADFS server by going this this URL:
This URL and login bypasses QuickHelp (or any relying party) and simply verifies whether you can log in to ADFS at all.
