How to Remove an Unwanted OneNote Notebook

Trying to figure out removing an Unwanted OneNote Notebook can be surprisingly frustrating. Unlike standard text documents, you cannot simply press a delete button while viewing the notebook inside the OneNote application interface. Microsoft structures OneNote so that the application only reads the notebook file; it does not host it. Therefore, the removal process must be handled in two phases: safely disconnecting the notebook from your active application, and then tracking down the source file on your cloud or local storage to permanently erase it. If you attempt to delete the source file while the application is still actively trying to sync it, you will encounter persistent synchronization errors. This guide explains the exact workflow required to completely eliminate an unwanted notebook from your digital workspace.

Disconnecting the Notebook from Your Application

Before you delete the actual file, you must tell the OneNote application to stop looking for it. If you skip this step, OneNote will continuously display a sync error icon next to the notebook's name, attempting to locate a file that no longer exists.

1. Launch your OneNote application on your desktop.
2. Locate the navigation pane on the left side of the screen where all your active notebooks are listed. If this pane is collapsed, click the notebook drop-down menu near the top left corner to reveal the full list.
3. Right-click the name of the unwanted notebook.
4. Select Close This Notebook from the context menu.

The expected result is that the notebook will instantly vanish from your application's navigation pane. This step confirms that the application has severed its connection to the file, but it does not delete your data. The actual notebook file still exists in its original storage location.

Permanently Deleting a Cloud-Synced OneNote Notebook

Most modern OneNote notebooks are automatically created and stored in Microsoft OneDrive. To completely remove the notebook, you must navigate to your OneDrive cloud storage directory and delete the source file.

1. Open a web browser and navigate to the official OneDrive website. Log in using the same Microsoft account associated with your OneNote application.
2. In the left-hand sidebar, click on My files.
3. Locate the folder where your notebooks are stored. By default, OneNote saves new notebooks in the Documents folder, though you may also have a dedicated Notebooks folder.
4. Scroll through your files until you find the notebook bearing the exact name of the one you just closed. It will feature a purple OneNote icon next to it.
5. Click the circular checkbox to the left of the notebook name to select it.
6. Click the Delete button located on the top command bar.

To verify the deletion, check the OneDrive Recycle Bin in the left-hand navigation pane. If you need the storage space immediately or want to ensure the data is permanently destroyed, click Empty recycle bin. Once emptied, the notebook is entirely irrecoverable.

Removing a Locally Stored Notebook

If you are using the older OneNote 2016 or OneNote 2021 desktop releases rather than the Windows 10/11 default app, you may have chosen to store your notebook locally on your computer's hard drive rather than in the cloud. The removal mechanism for local storage requires using the Windows File Explorer.

1. Ensure you have already closed the notebook within the OneNote application as detailed in the first section.
2. Open File Explorer on your Windows computer.
3. Navigate to your default document directory by clicking Documents in the left-hand quick access pane.
4. Locate and open the folder named OneNote Notebooks.
5. Find the folder that matches the name of your unwanted notebook. Unlike cloud notebooks which appear as a single file, locally stored notebooks are generated as entire folders containing individual section files.
6. Right-click the entire folder and select Delete (or click the trash can icon).

Verify this action by opening your Windows desktop Recycle Bin and emptying it. Your local notebook is now permanently removed from your hard drive.

Storage Type	Default File Location	Format to Delete
OneDrive (Cloud)	My files > Documents	Single URL/Shortcut File
Windows Local Drive	C:\Users\[User]\Documents\OneNote Notebooks	Entire Folder containing .one files

Managing Exported Notes with WPS Office

Because OneNote notebooks are heavily locked into Microsoft accounts and proprietary cloud administration services, WPS Office cannot directly access your OneDrive to delete or modify those Microsoft-side sync settings. However, if you are actively removing OneNote notebooks because you want to migrate to a less restrictive, offline-friendly document environment, WPS Office provides an excellent workflow for managing your exported notes.

Before deleting your unwanted notebook entirely, you can open it in OneNote and use the File > Export menu to save your pages as standard PDF or Word documents. Once exported, you can open these files directly in WPS Office. WPS Office utilizes a lightweight, tabbed interface, allowing you to open your exported notes, spreadsheets, and presentations in a single window while retaining control over local file storage. If your exported notes are in PDF format, you can utilize the WPS PDF editing tools to highlight text, add annotations, or seamlessly convert those old notes back into editable Word documents for future updates, completely free of the Microsoft ecosystem.

Frequently Asked Questions

Why does my deleted notebook still show up in search results or recent lists?

Even after deleting the source file from OneDrive, the OneNote application retains a cached memory of your recent activity. To clear a deleted notebook from your recent lists, right-click the dead link in your recent notebooks menu and select Remove from list. It may take up to 24 hours for cloud search indexes to fully purge the deleted file's metadata.

How can I recover a notebook I accidentally deleted?

If the notebook was synced to the cloud, log into the OneDrive website and click on the Recycle bin in the left-hand navigation pane. Select your deleted notebook and click Restore. Once restored, you will need to open the OneNote application, go to File > Open, and navigate to your OneDrive Documents folder to reopen the notebook and resume syncing.

Will deleting a shared notebook remove it for everyone else?

Yes. If you are the original owner who created and hosted the notebook on your personal OneDrive, deleting the source file permanently revokes access for all collaborators. They will receive a sync error the next time they open their application. If you only want to leave a notebook someone else shared with you, simply right-click it in your app and choose Close This Notebook; do not attempt to delete the source file.

Does uninstalling the OneNote application remove my notebooks?

No. Uninstalling the OneNote application from your computer or mobile device only removes the software used to view the files. Your actual notebooks remain safely stored in your Microsoft OneDrive account or your local Windows Documents folder. You must manually delete the files from those storage locations to permanently remove the notebooks.
