Use OneDrive Restore to Recover Previous Notebook States
If your OneNote files were connected to OneDrive but got corrupted or lost, you can roll back your entire OneDrive to a previous point in time to recover the notebooks.
OneDrive Restore allows Microsoft 365 subscribers to undo all actions that occurred on files and folders within the last 30 days. This is highly effective if the notebook structure was accidentally altered or deleted during the reset.
Log in to the OneDrive website using the Microsoft account associated with your OneNote notebooks.
Click the Settings (gear) icon at the top right of the screen, then select 'Restore your OneDrive'.
Choose a date from the dropdown menu (e.g., 'Yesterday' or 'Custom date and time') that falls before you reset the OneNote application.
Review the activity chart to find the specific changes, select the activities you want to undo, and click 'Restore' to revert your files.

Switch to OneNote Desktop to Maintain Local Backups
To prevent future data loss from app resets, switch from OneNote for Windows 10 to the standard OneNote Desktop app, which supports local caching and backups.

Frequently Asked Questions
Why did my notes disappear when I reset OneNote for Windows 10?
OneNote for Windows 10 relies entirely on cloud synchronization and does not store independent backup files on your hard drive. Unsynced notes are kept in a temporary app cache. When you reset the application via Windows settings, this cache is permanently deleted, taking any unsynced notes with it.
Can I recover OneNote files that were never synced to OneDrive?
Unfortunately, if the missing content was only stored in the local cache of OneNote for Windows 10 and never successfully reached the OneDrive servers before the app was reset, it is permanently lost and cannot be recovered.
How can I prevent losing my OneNote notebooks in the future?
Always ensure the sync status icon shows a cloud with a checkmark before closing the app. For maximum security, switch to the standard OneNote Desktop application (OneNote 2016), which allows you to create physical local backups and export your notebooks.
How do I know if my notes are safely synced to OneDrive?
You can verify your sync status by logging into OneNote.com through a web browser. If you can see your latest notes on the web version, they are safely stored in OneDrive and will survive a local app reset.
