How to Fix OneNote Error E0000024 When Saving or Syncing Notebooks

Product: Microsoft OneNote
Device & OS: not provided
Scenario: Attempting to save or synchronize a notebook that has been offline or unsynced for an extended period, such as a month.
Observed behavior: The notebook fails to synchronize, displaying error E0000024, preventing new or offline notes from securely backing up to the cloud storage.

Before you start

Verify that your local, unsynchronized notes are still accessible on your desktop. Do not prematurely close or log out of the affected notebook, as this will permanently delete any notes that have not yet been synced to the server.

Solution 1Recommended

Force Sync via OneNote for the Web

Opening the notebook from the web version and forcing it to open in the desktop app can refresh the synchronization connection.

This method is highly effective for re-establishing the authentication token between your desktop application and the OneDrive servers.

Access OneNote Web

Open your preferred web browser, navigate to OneNote for the web, and sign in with your Microsoft credentials.

Open the Notebook Online

Locate and open the specific notebook that is experiencing the E0000024 sync error.

Open in Desktop

Click the 'Open in Desktop App' button located in the top ribbon menu. This will prompt your local OneNote application to re-link with the cloud version and attempt to push the pending synchronization.

Authentication check: Ensure you are signed into the exact same Microsoft account on both the web browser and your desktop application.

Solution 2

Migrate Data to a New Notebook

If the sync connection is permanently corrupted, copying your unsynchronized data to a brand new notebook is the safest way to prevent data loss.

Frequently Asked Questions

Why does OneNote error E0000024 occur?

This error typically triggers when a notebook has been kept offline for an extended period, leading to an authentication timeout, server conflict, or a corrupted local cache when the application tries to re-establish the connection to OneDrive.

Will I lose my notes if I close a notebook that hasn't synced?

Yes, closing a notebook with unsynchronized changes in the desktop app will permanently delete those local offline changes. Always manually copy unsynced sections to a new, successfully synced notebook before closing the original one.

How can I check if my notebook is stored in a personal or business OneDrive?

In the OneNote desktop application, go to File > Info. Next to your notebook's name, review the URL path. If the path contains 'sharepoint.com' or 'my.sharepoint', it is stored in OneDrive for Business. Otherwise, it is typically hosted on a personal OneDrive account.

Does this error affect all my notebooks or just one?

Error E0000024 usually affects specific notebooks rather than the entire application. You can verify this by checking the sync status of your other open notebooks by navigating to File > View Sync Status.
