So I had updated to the most recent windows update on my desktop and I started having sync issues with OneNote. The specific error was:
"We need the password to sync this notebook. (Error code: 0xE0000024)"
I browsed around online and saw that deleting the cached user credentials was a possible solution. Tried it and it still wasn't working. I had originally made the changes on my laptop, and my laptop was syncing fine. But, then I saw that someone said to make sure to update to the most recent Windows update to solve the solution and I updated on my laptop. Immediately after installing the update on my laptop, it started giving me the error message when I tried to sync on my laptop.
I'm guessing something in the new Windows update broke OneNote sync? Anyone else having similar issues after the update or is it just me?
