Update Microsoft Office to Apply the Official Patch

Since this is a recognized software bug by Microsoft, the best and only permanent solution is to install the latest application updates once the fix is released.

Microsoft has officially acknowledged the issue where OneNote incorrectly limits the navigation bar to three section tabs. Their development team is actively working on a resolution.

Until the patch is automatically applied, you can manually check for the latest Office updates to ensure you receive the fix as soon as it becomes available.

1
Open Account Settings

Launch Microsoft OneNote and click on the 'File' tab in the top-left corner, then select 'Account' from the left-hand navigation pane.

2
Check for Updates

Under the 'Product Information' section, click on the 'Update Options' button.

3
Install Updates

Select 'Update Now' from the dropdown menu. Office will check for the latest versions and install any available patches.

Temporary Workaround: While waiting for the update to roll out, you can continue accessing your hidden sections by clicking the down-arrow icon located immediately to the right of the third visible tab.

Frequently Asked Questions

Can I change a setting to force OneNote to show more than three tabs?

No, this is not a settings issue. It is a known bug in the OneNote interface, meaning no user-facing configuration can override the three-tab limit at this time.

Will uninstalling and reinstalling OneNote fix the missing tabs?

Reinstalling the application is unlikely to resolve the issue because the bug exists in the current build of the software itself. You must wait for Microsoft to release a corrected version.

Are my missing sections deleted or lost?

No, your data is perfectly safe. The sections still exist but are temporarily hidden from the top navigation bar. You can access them by clicking the small down-arrow next to the third tab.
