Sharepoint Connected System Doesn't work OOTB, Required Work Around

Certified Lead Developer

Was not able to get the SharePoint connected system to work out of the box with client authentication.  I think this is due to a change on the SharePoint online side and I had to make some config changes based on this thread:

SharePoint Online authorization issue 'Token type is not allowed' - SharePoint Stack Exchange

Get started with the SharePoint Online Management Shell | Microsoft Docs

Just FYI for anyone running into 401 errors.

Maybe Appian can update the connected system and documentation to use an Azure Enterprise App instead of the old school SharePoint apps.
