Just over a week ago, Microsoft tech support got us all connected to syncing files down to our computers using the sync preview for ODfB. It was working flawlessly UNTIL I came in on Monday to discover most of the files and folders had been deleted off the online drive. Subsequently, all synchronized computers lost these files as well. (not a happy moment)
Since I'm the one who uploads the files, I assumed I may have inadvertently deleted some files. I found the deleted files in my computer's recycle bin and restored them and began uploading the files to ODfB. BUT THEN TODAY, I just discovered that each user's computers also have the deleted files in each of their recycle bins.
What mechanism would cause this to happen? How did the deletion occur? Where did it occur (cloud or local)? Is there any way to know?
