How can I delete all of OneNote and start over. I imported my notes from Evernote and I realized it would be much better to those a few at a time instead of all at once. Plus something happened with Quick Note because I keep getting a message to move it so it synchs. I have followed the message and it doesn't work. Now I get an undefined error. So, I think delete it all and start over is the best approach. How do I do it? Installed OneNote 2016 on Windows 8.1 system with Office 2007.
