How to Fix OneNote Notebooks Appearing Empty and Failing to Sync
Question details
The user needs to restore missing content in the OneNote desktop application and resolve a synchronization failure that causes new sections to disappear.
- Product
- Microsoft OneNote
- Device & OS
- not provided
- Scenario
- Viewing and synchronizing OneNote notebooks using the desktop client.
- Observed behavior
- Notebooks appear empty in the desktop app despite being accessible online. Creating new sections results in them being deleted after synchronization fails, commonly accompanied by error 0xE00009C8.
Before troubleshooting the desktop application, log into OneNote for the Web to verify that your notebook data is intact and successfully saved online.
Check Notebook Sync Status and Force Synchronization
Manually checking the sync status helps identify specific errors and force the notebook to synchronize with the cloud.
Sometimes the automatic synchronization process pauses or encounters a temporary block. Manually forcing the sync can push pending changes through and reveal specific error codes like 0xE00009C8.
Launch the OneNote desktop application. Click on 'File' in the top ribbon menu and select 'Info'. Click on the 'View Sync Status' button to open the Shared Notebook Synchronization dialog.
Locate the problematic notebook in the list and click 'Sync Now' next to it to force the synchronization process.
Resolve Sync Error 0xE00009C8 via OneNote for the Web
If the desktop app repeatedly deletes sections during sync, you can bypass the error by creating sections directly in the web version and forcing a fresh download.

Frequently Asked Questions
What does OneNote sync error 0xE00009C8 mean?
Error 0xE00009C8 typically occurs when the OneNote desktop application struggles to communicate with OneDrive servers due to network issues, a corrupted local cache, or server-side throttling, which prevents new changes from syncing to the cloud.
How do I recover a OneNote section that disappeared after syncing?
Check the 'Deleted Notes' section under the 'View' tab in the desktop application. Additionally, log into OneNote for the Web to see if the section successfully synced to the cloud before it disappeared from the local application.
Will closing a OneNote notebook delete my unsynced data?
Yes, if you close a notebook that has not successfully synchronized with OneDrive, any unsynced changes or new sections made locally will be permanently lost. Always copy your unsynced notes to a separate document as a backup before closing the notebook.
How do I clear the OneNote cache to fix sync issues?
Ensure OneNote is completely closed. Press Windows + R, type '%localappdata%\Microsoft\OneNote', and press Enter. Open the folder corresponding to your software version (e.g., '16.0') and delete the 'cache' folder. The cache will rebuild automatically when you restart OneNote.
