When I use the Open With Explorer view of a SharePoint library and open a document from there, I am prompted to Check Out & Open (or just open) the file. And then from the open file, under the File menu, I have an option for SharePoint / Office 365 Server, to check the file back in and/or to update Document Properties. This is the exact functionality I am looking for. My question is, why don't I have this option when I open the PDF in one of these scenarios:
- direct from the browser (within SharePoint)
- from a synced library
- outside of SharePoint (i.e. from the Desktop)
