The user is experiencing an issue where OneNote notebooks that have been deleted or removed from the Open Notebook list continue to reappear automatically.

How to Fix Deleted OneNote Notebooks Reappearing in the Open List

Product: Microsoft OneNote
Device & OS: not provided
Scenario: Removing obsolete or deleted notebooks from the Open Notebook list to keep the workspace organized.
Observed behavior: Deleted notebooks persistently reappear in the list, which is often caused by their saved paths containing an invalid caret character, such as a path ending in ^.Documents.

Before you start

Ensure you have fully synced all your active notebooks and backed up any important notes before attempting to clear application caches or update system settings.

Solution 1Recommended

Update OneNote and Windows OS

Since this behavior is associated with an older OneNote bug that mishandled invalid notebook paths, updating your software is the most reliable first step.

Removing the entry from the list manually may not permanently resolve the issue if the underlying bug still exists in your current software version. Updating both Microsoft Office and Windows ensures you have the latest patches.

Open OneNote Account Settings

Launch Microsoft OneNote, click on 'File' in the top ribbon, and navigate to the 'Account' tab located at the bottom left.

Check for Office Updates

Under 'Product Information', click on the 'Update Options' drop-down menu and select 'Update Now'.

Update Windows OS

Press the Windows key, type 'Check for updates', and hit Enter. Download and install any pending Windows updates.

Contact Microsoft Support

If the invalid notebook entries continue to return after updating, contact Microsoft Support directly, as there may be no user-accessible fix for certain corrupted cloud states.

Bug Limitation: Because this issue often stems from cloud-synced invalid path strings, a local fix might only be temporary until the cloud cache is purged by Microsoft.

Solution 2

Clear the OneNote Local Cache

Clearing the local application cache can sometimes forcefully reset the recent notebook list and temporarily remove corrupted paths.

Frequently Asked Questions

Why do deleted notebooks reappear in my OneNote Open list?

This is typically caused by a known bug in older versions of OneNote where notebook paths contain an invalid caret character (like ^.Documents). The application fails to properly process and clear these invalid entries from its recent list during synchronization.

Can I manually edit the Windows Registry to remove these invalid OneNote paths?

While advanced users can sometimes remove recent list items via the Registry Editor under the Office OneNote keys, invalid path bugs often cause the entries to regenerate automatically upon your next sync. Updating the application is a safer and more effective approach.

Will uninstalling and reinstalling OneNote permanently fix the reappearing notebooks?

It might not permanently fix the issue if the invalid notebook path is tied to your Microsoft account and synced via OneDrive. Ensuring both the local application and your Windows OS are fully updated is required to resolve underlying bug logic.
