- Product
- Microsoft OneNote 2016
- Device & OS
- not provided
- Scenario
- Syncing and viewing a large notebook across desktop, web, and mobile platforms.
- Observed behavior
- Sections and pages beyond a certain point disappear in the desktop app but remain fully accessible on the web version.
Log into OneNote for the web to confirm your missing sections and pages are safely stored online. Do not attempt to reset, repair, or delete the local notebook before verifying that the web version holds all your up-to-date data.
Force a Fresh Synchronization from the Web
Because the content is verified as safe online, forcing the web application to push a fresh copy to the desktop app is the safest way to resolve local cache corruption.
OneNote stores a local cache of your notebooks to allow offline editing. When this cache becomes corrupted or fails to sync properly, sections may appear missing on the desktop. Opening the notebook directly from the web forces the application to rebuild this connection.
Ensure OneNote 2016 is completely closed on your computer so it does not interfere with the new sync command.
Log into OneNote online using your browser and navigate to the specific notebook that has missing sections.
Click the 'Open in Desktop App' button located in the top ribbon menu. This will launch OneNote 2016 and prompt it to download the notebook fresh.
Leave the desktop application open and do not click through the sections immediately. Wait for the green sync icon over the notebook to finish spinning, indicating the download is complete.
Reduce Notebook File Size
Notebooks approaching or exceeding 2 GB can trigger synchronization failures in OneNote, leading to missing sections.

Frequently Asked Questions
Why did sections disappear in OneNote 2016 but remain visible online?
This happens when the local desktop cache becomes corrupted or fails to sync properly due to a network interruption or file size limit. The cloud version acts as the master copy and remains unaffected by local desktop glitches.
Is there a maximum file size limit for OneNote notebooks?
Yes, notebooks stored on OneDrive or SharePoint generally have a 2 GB file size limit. Exceeding this limit often causes the desktop application to stop syncing correctly, which can result in missing sections.
Where does OneNote 2016 store its local backups?
By default, OneNote 2016 stores local backup files at 'C:\Users\[YourUsername]\AppData\Local\Microsoft\OneNote\16.0\Backup'. You can check this folder to see if older versions of your missing sections were preserved locally.
