Sync Unsaved Notes via OneNote for the Web
Manually transfer unsynchronized sections to the web version of OneNote and force a fresh sync to your desktop application.
This method forces a reconnection between the cloud server and your desktop client. By copying your unsynced notes to the web version first, you protect your data from being overwritten or lost when the desktop application is closed.
Open your web browser, log in to your OneDrive for Business or SharePoint Online account, and open the affected notebook in OneNote for the web.
Compare the web version of the notebook with your desktop application to identify exactly which sections or pages have failed to sync.
Manually copy the text, images, or sections from your desktop application that did not sync, and paste them into the corresponding pages in OneNote for the web.
Once you have verified that all recent work is safely stored in the web version, close the OneNote desktop client completely.
In OneNote for the web, click the 'Open in Desktop App' button on the ribbon. This will launch your desktop client and force it to establish a new, synchronized connection with the cloud server.
