+ 0 Votes thanks but I've tried most of that ebecca 7 years ago I have new computer, so I don't think software compatibility is the issue. My hard drive was recently defragged and does not appear to need further defragging. I've performed a repair. Do you have any idea what Office is even doing when it "synchronizes" my files? Since I use only one computer, what is it synchronizing? Is there a name for the synchronizing function - could I uninstall that function? Thanks again.
