I am trying to add Access Database files to a SharePoint page, and I have encountered several issues: .accdb files are not supported when uploaded and links to shared drives are not accepted in a quicklink section or as a hyperlink in a text box (file://domain/X:/folder/doc.accdb).
So far, I tried changing formatting on the file link (forward- v. back-slashes) and uploading short-cuts of the files (SharePoint tries to open .accdb file in browser). It is preferable that the file use the shared drive versus having a copy of the file on SharePoint that is not linked/connected to the original.
