We're working on a Microsoft Outlook add-in that we're looking to put into the Office marketplace. We've been failed on our review with
"1120.3.6.39 SSO Functionality"
Please implement a fallback method for single sign on (SSO) for cases when users of the add-in are on hosts that don’t support SSO or SSO doesn’t succeed for other reasons. Additional information on fallback methods can be found in the documentation. https://learn.microsoft.com/en-us/office/dev/add-ins/develop/sso-in-office-add-ins?view=word-js-preview#requirements-and-best-practices
We've not been able to recreate this in our environment. We believe in test that failed was on Desktop Outlook on Windows 10. Is there a way of recreating this so SSO will not succeed so it will trigger our fallback code?
