shared a file with someone and she emailed me back she cannot edit a Word file. For testing purposes I created a file in MS Word 2010, uploaded it on the Sky Drive, clicked "Share", "Everyone who have link can share", it generated link

I can download file, "Share" button just shows me as an owner, but I cannot edit at all!  Am I doing anything wrong? I have seen some similar discussions on this forum, unfortunately none of them has been resolved.
