How to Recover Unsynchronized OneNote Notes from Local Cache
Question details
The user needs to retrieve OneNote notes that failed to synchronize and might only be stored temporarily in the application's local cache.

- Product
- Microsoft OneNote
- Device & OS
- not provided
- Scenario
- Experiencing synchronization failures in OneNote resulting in notes not being uploaded to the cloud.
- Observed behavior
- Notes created during the sync failure are missing from the main cloud notebook but may still temporarily reside in the local cache, requiring careful extraction before the cache is wiped.
Before attempting any recovery steps, immediately locate and back up your entire OneNote local cache folder to a safe location (like your Desktop) to prevent accidental data overwriting.
Manually Extract and Copy Unsynchronized Notes
Safely extract your recovered pages from the cached offline notebook and transfer them into a new, properly synchronized notebook.
The local cache holds temporary data until you sign out or reset the application. Attempting to copy unsynchronized data at the section level generally fails, so you must extract the data page by page.
Open the OneNote application without signing out of your account to ensure the local cache remains active and accessible offline.
Click 'File' > 'New' to create a brand-new, empty notebook. Ensure it is actively and successfully syncing to your cloud account.
Navigate to the unsynchronized notes. Right-click each recovered page individually, select 'Move or Copy', and choose the newly created synchronized notebook as the destination. Repeat this for all missing pages.

Use Data Recovery Software for Deleted Cache
Use this method if the cache folder was already deleted due to a sign-out or app reset and you need to restore the underlying files.

Frequently Asked Questions
Why can't I copy my unsynchronized OneNote sections directly?
Unsynchronized sections often contain corrupted or incomplete data structures that cause section-level copying to fail. You must copy your notes page by page into a new synchronized notebook to ensure the data transfers correctly.
Where is the OneNote local cache folder located on Windows?
On Windows, the cache is typically located at C:\Users\[YourUsername]\AppData\Local\Microsoft\OneNote\[Version]\cache. Navigating here allows you to manually copy and back up the cache folder before attempting any troubleshooting.
What happens to my unsynchronized notes if I sign out of OneNote?
Signing out of your account or resetting the OneNote application automatically deletes the local cache folder. If your notes were not synced to the cloud before doing this, they will be permanently lost unless you made a manual backup.
Can I open a copied OneNote cache file directly?
No, OneNote cache files cannot be opened directly by double-clicking them like standard document files. The data must be read organically by the OneNote application in its original cache state, and then the content must be copied out into a standard notebook.
