Product

Device & OS
not provided
Scenario
Attempting to create a complete backup of a notebook by exporting it to a .onepkg file from the desktop application.
Observed behavior

Before you start

Ensure you have a stable and active internet connection so the desktop application can successfully download the latest notebook changes from the cloud server.

Solution 1Recommended

Force Full Synchronization in the Desktop Application

Resolve the incomplete export issue by manually forcing a full synchronization of your notebook sections before attempting the export.

When you export a notebook, OneNote uses the locally cached data. If sections haven't fully downloaded from OneDrive, the local cache is incomplete, which triggers the partial backup warning.

1
Open OneNote Desktop

Launch the OneNote desktop application and navigate to the specific notebook you are trying to export.

2
Trigger Manual Sync

Right-click the name of the notebook in the notebook list and select 'Sync This Notebook Now', or simply press the Shift + F9 keys on your keyboard.

3
Verify Synchronization Status

Right-click the notebook name again and select 'Notebook Sync Status'. Wait for the progress bar to complete and ensure the status displays as 'Up to date'.

4
Export the Notebook

Go to File > Export. Under 'Export Current', select 'Notebook'. Choose 'OneNote Package (*.onepkg)' under 'Select Format', and click the 'Export' button. You should no longer receive the unsynced sections warning.

Force Full Synchronization in the Desktop Application
Avoid Partial Backups: If you click 'Yes' to continue when prompted about unsynced sections, your exported file will permanently lack those missing pages. Always ensure full synchronization for a complete backup.

Frequently Asked Questions

Why does OneNote say sections have not fully synchronized during export?

This happens when the local cache of your OneNote desktop application has not finished downloading the latest changes from OneDrive. Because the export relies on local data, unsynced pages cannot be included in the file.

What happens if I continue exporting with unsynced sections?

If you bypass the warning and continue, OneNote will generate a partial .onepkg file. Any pages or sections that were not fully synchronized will be permanently excluded from this backup.

How can I check if my OneNote notebook is completely synced?

You can check the sync status by right-clicking the notebook name and selecting 'Notebook Sync Status'. If the window displays 'Up to date' with a green checkmark next to your notebook, it is fully synced.

Can I export a complete notebook as a .onepkg file from OneNote for Web?

No, exporting a notebook as a complete .onepkg package is only supported in the OneNote desktop application for Windows. The web version does not support this specific export feature.
