Question details

The user is experiencing a synchronization issue in OneNote where a specific page fails to upload to the cloud.

Product: Microsoft OneNote
Device & OS: not provided
Scenario: Attempting to sync OneNote notebooks across devices or trying to access notes via the web browser.
Observed behavior: OneNote displays a 'Page has never been synced' error. The notebook cannot be opened in OneNote for the web (returning a 404 error) and is not visible in OneDrive, although local backups appear to exist.

Before you start

Before making any changes or resetting your synchronization settings, copy the text of any unsynchronized notes into a temporary local file (like Notepad or Word) to prevent permanent data loss.

Solution 1Recommended

Create a New Notebook and Transfer Your Unsynced Notes

This method establishes a fresh, properly synced notebook directly in OneDrive, allowing you to bypass the corrupted synchronization link of the old notebook.

When a notebook encounters a persistent 404 error online, it usually means the cloud version is corrupted or missing. Creating a new cloud notebook and transferring your local data into it is the most reliable way to force a new sync.

Create a new notebook in OneDrive

Log into your OneDrive account through your web browser and create a brand new OneNote notebook directly within the cloud storage interface.

Open the new notebook in the desktop app

While viewing the newly created notebook in OneNote for the web, click the 'Open in Desktop App' button to launch it in your local OneNote application.

Transfer sections and pages

In your desktop app, navigate to the notebook showing the sync error. Right-click the problematic pages or sections and select 'Move or Copy'. Choose the newly created notebook as the destination.

Manually copy notes if the transfer fails

If the automatic move/copy function fails, manually select the text within the unsynced pages, copy it, and paste it directly onto new pages within the new notebook.

Verify synchronization

Wait a few minutes for OneNote to process the changes. Check OneNote for the web to confirm that the new notebook has updated and the pages are now visible online without errors.

Additional Troubleshooting: If the new notebook also fails to synchronize, verify that you have not exceeded your OneDrive storage limit and ensure you are using the latest version of the OneNote application.

Frequently Asked Questions

Why does OneNote say my page has never been synced?

This error usually occurs when there is a disruption in the connection between your local OneNote application and OneDrive, corrupted notebook sections, or insufficient cloud storage space.

Where are OneNote local backups stored on Windows?

By default, OneNote local backups on Windows are typically located in the AppData folder at C:\Users\[YourUsername]\AppData\Local\Microsoft\OneNote\[Version]\Backup.

How can I check if my OneDrive storage is full?

Log into your OneDrive account through a web browser and check the storage indicator at the bottom left of the screen. If it is full, OneNote will not be able to sync new pages until you free up space.

Can a 404 error in OneNote for the web be fixed?

A 404 error means the file cannot be found on the server. If the notebook failed to upload initially, you must recreate the notebook in OneDrive and transfer your locally cached data into it to resolve the error.
