A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
I may have actually solved my own problem. In registry editor I searched for every occurrence of "One Drive" and "OneDrive" and maliciously deleted all but a few of them. I think there were more than a hundred. How does all that get into my registry? So far, no more annoying reminders in Word and Excel, which have become excellent tools.
My thanks to Microsoft for providing regedit, the tool that fixes the other tools. Now, if only they could do something about the second most horrible programming language ever created... Maybe discontinue it and replace it with a real programming language like FORTH, APL, ADA, or ATLAS....
