Is It Safe to Reinstall OneNote Without Losing Notebooks?
Question details
The user wants to know if uninstalling and reinstalling the OneNote desktop app will delete their notebooks after experiencing synchronization errors.
- Product
- Microsoft OneNote
- Device & OS
- Windows 10
- Scenario
- Attempting to fix OneNote synchronization issues and missing pages by reinstalling the local application without losing important notes.
- Observed behavior
- OneNote for Windows 10 is missing updates and failing to display notebooks locally, although the notebooks remain fully accessible through OneDrive and OneNote for the Web.
Log into OneNote for the Web or your OneDrive account through a browser to verify that your most recent notes are visible and fully synced to the cloud.
Verify Sync Status and Reinstall OneNote
If your notebooks are securely stored and visible in OneDrive, it is completely safe to remove the local application.
Because OneNote notebooks are tied to your Microsoft account and stored in the cloud, uninstalling the app only removes local cached files. As long as your data is synced, you will not lose anything.
Open a web browser, navigate to onenote.com, and sign in. Check your notebooks to ensure all recent changes are present.
Right-click the Start menu, select 'Apps and Features', scroll down to locate OneNote, click on it, and select 'Uninstall'.
Open the Microsoft Store, search for 'OneNote', and click 'Install'. Once installed, launch the app and sign back in to download your notebooks from the cloud.

Frequently Asked Questions
Where are my OneNote notebooks stored locally on Windows 10?
For the OneNote for Windows 10 app, notebooks are primarily stored in the cloud via OneDrive, with temporary cache files hidden in your local AppData folder. If you use the classic OneNote desktop application, local backups are typically found in your Documents folder under 'OneNote Notebooks'.
Will I lose my unsynced notes if I reset the OneNote app?
Yes. If you have notes that have not successfully synchronized to OneDrive, resetting or uninstalling the OneNote for Windows 10 app clears the local cache, permanently deleting those unsynced changes. Always manually export or copy unsynced content first.
How can I force OneNote to sync before uninstalling?
Right-click the name of your notebook in the left sidebar and select 'Sync This Notebook Now', or press Shift+F9 on your keyboard. Watch the sync status icon to confirm it finishes without displaying an error triangle.
Why are my notebooks visible on the web but missing in the desktop app?
This usually indicates a local synchronization glitch, a corrupted cache, or an issue with your account credentials in the desktop app. Since your data is safe on the web, signing out and back into the local app, or reinstalling it entirely, generally fixes the display issue.
