Observed behavior
The desktop application displays an error stating the package file is corrupt or empty and fails to sync, even though the notebook can still be opened successfully via OneNote for the web.

Solution 1Recommended

Use OneNote for the Web and Force Sync

Since the desktop app is experiencing known synchronization issues with OneDrive, using the web version ensures your data is accessible while you manually trigger a sync.

Microsoft frequently investigates backend synchronization issues affecting OneDrive and OneNote desktop clients. Bypassing the local client temporarily is the safest way to access your notes without risking data loss.

1
Access via Web Browser

Open your preferred web browser, navigate to OneDrive, and log in with your Microsoft account credentials.

2
Open in OneNote for the Web

Locate the problematic notebook in your OneDrive files and click to open it in OneNote for the web. Verify that your latest changes are intact.

3
Force Sync in Desktop App

Return to the OneNote desktop application, right-click the name of the notebook experiencing the error, and select 'Sync This Notebook Now' from the context menu.

Use OneNote for the Web and Force Sync
Avoid Reinstalling or Modifying Files: Do not repeatedly uninstall OneNote or aggressively edit the original notebook until the synchronization issue is fully resolved by Microsoft, as this may lead to permanent data loss.

Frequently Asked Questions

Why does OneNote say my package file is corrupt?

This is often a false positive error caused by a temporary synchronization failure between the OneNote desktop app and OneDrive servers, rather than actual corruption of your notebook file.

Is my OneNote data lost if the desktop app won't open it?

Usually, your data remains perfectly safe. You can easily verify this by logging into your OneDrive account through a web browser and opening the notebook directly in OneNote for the web.

Should I reinstall OneNote to fix the sync error?

No, it is not recommended to reinstall OneNote or clear your local application cache immediately. Doing so before the server-side sync issue is resolved might permanently delete any notes that haven't been backed up to the cloud.
