How to Fix OneNote Sync Error 0xE00009C8 bb0ur on a New Computer

Product: Microsoft OneNote
Device & OS: not provided
Scenario: Setting up OneNote on a new computer and attempting to sync existing notebooks from OneDrive.
Observed behavior: OneNote fails to synchronize the notebooks and displays the specific error code 0xE00009C8 bb0ur even when storage is available.

Before you start

Ensure you have a stable internet connection and verify that your Microsoft account is properly signed in to both OneDrive and OneNote. It is highly recommended to locally back up any recently added unsynced notes to a separate document before forcing a sync.

Solution 1Recommended

Manually Force Synchronize the Notebook

Since this is a known issue addressed by the OneNote team, forcing a manual synchronization process will typically push the connection through and resolve the error.

This error is a recognized synchronization glitch that can occur even when your OneDrive storage has plenty of space. The most effective workaround provided by Microsoft is to manually trigger the sync process from the desktop application.

Open the OneNote Desktop App

Launch the OneNote desktop application on your new computer and navigate to the notebook that is currently failing to sync.

Sync This Notebook Now

In the left-hand notebook list panel, right-click the name of the problematic notebook and select 'Sync This Notebook Now' from the context menu.

Use the View Status Menu

Alternatively, navigate to the top ribbon and click on 'File', then select 'Info'. Click on the 'View Sync Status' button, and in the prompt that appears, choose 'Sync All' to force update all your open notebooks.

Protect Unsynced Data: If you have offline edits that haven't synced yet, manually copy and paste those specific pages into a temporary local document (like Notepad or Word) to prevent any accidental data loss during the manual sync.
