Hi 小西,
Good day and welcome to the community. Please could you let me know which platform are you having issue with OneNote syncing? Below are the steps to resolve syncing issue on Windows:
Set notebooks to sync automatically:
- Select the File menu and choose Options.
- Select the Sync tab and check the box next to Sync notebooks automatically.
Manually sync notebooks:
- Select the File menu and on the Info tab, select
View Sync Status.
- In the Shared Notebook Synchronization dialog box that appears, do one of the following:
- Select Sync All to sync all of your shared notebooks.
- Select Sync Now next to a specific notebook to sync only that notebook.
If you still have sync issues and your notebook is stored on OneDrive or on newer versions of SharePoint, try opening the notebook at www.onenote.com to help determine if the problem is caused by the server or by OneNote.
If you are having sync issues on other platforms, refer to Fix issues when you can't sync OneNote - Microsoft Support for more information.
I hope this can help!
Sincerely,
Nam-D - MSFT | Microsoft Community Support Specialist.
