Hello! 

Our business process uses The Form Assembly(tfa) to gather information and create a case record in Salesforce. One of the data points inputted is a file stored in Sharepoint. I also have Files Connect for Sharepoint Online set up and running. Currently when the user hits submit on tfa, the file is posted as a new chatter feed on the related case. Salesforce recognizes that the file is from Sharepoint, however when I click "Open" (to open in SPO) I get an error -- "Object not found.Either this item has been deleted or you lack access to it."  I'm sure I have access to the file on Sharepoint as I am the owner of it.

If I manually attach the file to the chatter feed via Files Connect, I am able to "Open" it in Sharepoint. I believe Laurent Kubaski refers to this as Static Linking. However, this is not what I want.

Any thoughts? Happy to provide screenshots, etc

Appreciate any help!
