Hello Jay,
Welcome to Microsoft Community.
To resolve this issue we need some information. Let us know the following.
- Where are your OneNote notebooks/data saved to?
- Are you syncing your OneNote Notebooks online to some location – like OneDrive? Where are you syncing your information?
This is an error which occurs when you are not able to sync your OneNote notebooks or sections/part of the notebooks to OneDrive or any other location online.
To resolve the issue create a new OneNote section. Copy and paste the contents from the section which does not sync and gives this error. Paste the contents copied to the new section. Then delete the section which is not syncing and giving the error and finally rename the newly created section. Check if this step resolves the issue.
