Related to this maybe(?), but I am looking for an overall site collection solution in SP O365. I want users to be able to send a link directly to a document but force the doc to open in MS Word client application, not Word Online. Settings are already in place so that if a user goes to the library and clicks on a document, it opens by default in the full client application.
By activating the feature You can force a user to open the document in the client application when clicking on the file i question. But it does not seam possible to force a user to open the file in an application by clicking a shared link.
