I have recently had a Sharepoint 2013 solution setup for my company, we use a document library for our customer documentation. All but one of our users can open/edit/save documents back into Sharepoint, the one user odd user out upon clicking either the edit button or directly clicking the doc link (we have it set to open in app from clicking) downloads the document to his pc, I have tried various suggestions I have seen on here around office trusted apps etc but cant seem to resolve this one atall.
The user is on Office 2010.
