The document is routed to the exceptions after the export to SharePoint is performed within the following error shown in the logs:
Document N (NN): File Name: <THE FILE NAME>: The remote server returned an error: (403) Forbidden.
The issue may occur if the SharePoint server was not available during the export. That is the intended way how FlexiCapture should behave.
Since SharePoint is a third-party platform that is not handled by ABBYY, there is nothing that can be configured on the FlexiCapture Cloud side.
