Question details

The user is trying to locate and restore OneNote notebook sections that disappeared from the desktop application following a software update.

Product: Microsoft OneNote
Device & OS: Windows laptop
Scenario: Accessing local or cloud-synced notebooks in the OneNote desktop application immediately after a software update.
Observed behavior: Previously available notebook sections appear to be completely missing or deleted from the OneNote interface, even though they have been used normally for years.

Before you start

Ensure you have a stable internet connection to allow OneNote to communicate with its servers, and verify that you are signed into the correct Microsoft account.

Solution 1Recommended

Force Sync the Notebook

Manually forcing a synchronization can resolve display issues if the update temporarily disrupted the connection to your notebooks.

Software updates can sometimes pause or interrupt background synchronization. Forcing a manual sync commands the desktop application to retrieve the latest notebook structure from the cloud or local cache.

Right-click the notebook

Open the OneNote desktop application, locate the affected notebook in the left-hand navigation pane, and right-click on its name.

Trigger manual sync

Select 'Sync This Notebook Now' from the context menu to force the application to update.

Use the Info menu (Alternative)

Alternatively, click the 'File' tab, select 'Info', choose 'View Sync Status', and click the 'Sync All' button to update all notebooks simultaneously.

Check Sync Status: If you see a green checkmark next to the notebook after syncing, the missing sections should reappear.

Solution 2

Restore Sections from Local Backup

If syncing fails, you can recover the missing sections directly from OneNote's automatic local backup folder on your C: drive.

Solution 3

Check Cloud Storage Locations

Verify if the sections are intact in your cloud storage (OneDrive or Dropbox) in case the local app was disconnected during the update.

Frequently Asked Questions

Why did my OneNote sections disappear after a software update?

Updates can sometimes clear the local cache or temporarily disconnect the application from your Microsoft account, causing the desktop app to display incomplete notebooks until a full sync is successfully performed.

How often does OneNote create local backups on my computer?

By default, the OneNote desktop application automatically backs up your notebooks once a week. You can adjust this frequency or trigger a manual backup by going to File > Options > Save & Backup.

Can I recover a OneNote section if I don't use OneDrive?

Yes. If you use the OneNote desktop version on Windows, you can retrieve your missing sections from the local automatic backup folder, typically located at C:\Users\[Username]\AppData\Local\Microsoft\OneNote.
