Hi,
Did you mean you add the OneDrive service in OneNote and try to upload Notebooks to the OneDrive account? This problem appeared when you are trying to sync Notebooks, is my understanding correct? If yes, please try this method to help you:
NOTE: Before making any changes, ensure you have a backup of your OneNote notebooks. You can do this by exporting your notebooks to a local drive.
- Clearing the OneNote cache can sometimes resolve synchronization issues. To do this, close OneNote and navigate to
C:\Users\<YourUsername>\AppData\Local\Microsoft\OneNote\15.0\
. Delete theOneNoteOfflineCache.onecache
file. Restart OneNote and let it resynchronize. - If the above steps don't work, you might need to recreate your OneNote notebook. Create a new notebook and copy the sections from the old notebook to the new one. This can help if the original notebook is corrupted. Then sync the new Notebook.
- You can try repairing your Office installation. Go to Control Panel > Programs > Programs and Features, select your Office installation, and choose "Repair."
