Access Denied for Anonymous Workflow Users

Q: Why do I recieve an access denied error when triggering only some of my flows from Microsoft Dynamics 365 CE

A: After the Experlogix Smart Flows 4.19.0 release, DocuSign and SharePoint supported authentication for Individual User Authentication. Since this required all users to be synced, the system provides an access denied error for any non-synced user who's only role is Xpertdoc Smart Flows Workflow Executor, for more information on User Types, see User Types.
