Since the security implications of OneDrive are nowhere explicitly stated, I choose not to use OneDrive. In fact, I used a DACL to deny access to OneDrive. That means I am constantly nagged about the inaccessibility of OneDrive. I wonder if Microsoft would deign to document what OneDrive is, what are the implications of its various configuration states, and why I benefit from using it. I read on its interface that certain settings cause files to vanish from my PC and end up on OneDrive. Why on earth would I want that to happen?  I haven't been all the meetings because I am not employed by
