- Product
- Microsoft OneNote
- Device & OS
- not provided
- Scenario
- Attempting to secure an entire notebook from being permanently deleted by requiring a code or locking mechanism.
- Observed behavior

Verify whether your OneNote notebook is stored locally on your device or synced to OneDrive, as this determines the most effective recovery and protection strategies.
Store the Notebook in OneDrive for Version History
Storing your notebook in OneDrive is the most reliable way to prevent permanent data loss, as it offers a Recycle Bin and version history to recover accidentally deleted files.
While OneNote cannot lock a notebook from being deleted, hosting it on OneDrive provides an excellent safety net. If a notebook is deleted, it is moved to the OneDrive Recycle Bin where it can be restored. Additionally, version history allows you to roll back changes.
In OneNote, go to 'File' > 'Share' and select your OneDrive account to move a local notebook to the cloud.
If a notebook is deleted, log in to the OneDrive website, navigate to the 'Recycle bin' on the left sidebar, select the deleted notebook, and click 'Restore'.
To recover earlier versions of your notes, right-click the notebook file in OneDrive, select 'Version history', and restore the desired previous version.
Configure Automatic OneNote Backups
Setting up frequent automatic backups ensures you always have a recent local copy of your notebook if the original file is deleted or corrupted.
Restrict OS-level Folder Permissions
Use Windows folder permissions to restrict users from deleting the directory where your local OneNote notebooks are stored.
Try WPS Office for Secure Cloud Saving and File Protection
If you are concerned about losing important documents, consider switching to WPS Office. It provides robust auto-save features, real-time cloud synchronization, and a seamless environment for all your office tasks without the fear of accidental data loss.

- 2. Install WPS Office: Run the downloaded installer and follow the simple on-screen instructions to set up the software on your computer.
- 3. Enable Cloud Sync: Open WPS Office, sign in to your account, and enable auto-saving to the WPS Cloud to protect your documents from accidental deletion.

Frequently Asked Questions
Can I password-protect an entire OneNote notebook?
No, OneNote only allows you to apply password protection to individual sections within a notebook, not the entire notebook file itself.
Does adding a password to a section prevent it from being deleted?
No. A password-protected section can still be deleted by anyone with access to the file without needing to enter the password. The password only prevents unauthorized viewing of the content inside.
Where do deleted OneNote notebooks go?
If your notebook is saved in OneDrive, a deleted notebook will go to the OneDrive Recycle Bin, where it remains recoverable for up to 30 days. If saved locally on your hard drive, it usually goes to your computer's Recycle Bin.
How often does OneNote automatically back up my notes?
By default, OneNote backs up your notebooks once a week. You can customize this frequency by navigating to File > Options > Save & Backup and adjusting the time interval.
