Resolve OneNote Error 0xE00009C8

To troubleshoot and fix the OneNote error 0xE00009C8 bb0r, consider the following steps. Before trying these solutions, ensure that your internet connection is stable.

1. Log out and then log back in to OneNote
2. Attempt to manually sync your notebooks
3. Clear the cache of OneNote
4. Create a new notebook
5. Access the notebook via your web browser
6. Repair the OneNote application
7. Uninstall and then reinstall OneNote

Each of these solutions is elaborated upon below.

1] Log Out and Back Into OneNote

Start by logging out of OneNote and then logging back in. Here’s how:

1. Launch OneNote and navigate to the File menu.
2. On the left menu, select Account.
3. Choose Sign out.
4. Close OneNote and reboot your computer.
5. Reopen OneNote and sign back in.

2] Manually Sync Your Notebooks

If signing out and back in does not resolve the issue, try syncing your notebooks manually by following these directions:

1. Open OneNote.
2. Select the File menu.
3. From the left menu, choose Info to view all your notebooks.
4. Click on Settings, then select Sync for the notebook that is experiencing issues.

Check if the problem remains after this step.

3] Clear OneNote Cache

A corrupted OneNote cache might lead to syncing problems. Clearing the cache could remedy this issue. To do so, open the Run command by typing appdata, then hit OK. This action will take you to the AppData folder. Next, navigate to the following path:

Local > Microsoft > OneNote > 16.0

Depending on the version of your Office suite, the folder may be labeled differently than 16.0. Ensure OneNote is closed before you delete the cache folder; it will be recreated the next time you launch OneNote.

4] Set Up a New Notebook

If you still encounter issues, create a new notebook and check if it syncs successfully. If it does, you can transfer your data from the faulty notebook to the new one. Right-click on each section of the problematic notebook and select Move or Copy. A window will appear; choose your newly created notebook and click Copy. This action will automatically generate a new section in the new notebook with the copied content. Repeat this process for all sections, and then you can safely delete the original notebook.

5] Access the Notebook via Web Browser

If prompted when you open the notebook in your web browser, accept the request. The notebook should then load in OneNote, and syncing should proceed without errors.

6] Repair OneNote

Should the error still persist, repairing OneNote may prove beneficial. Follow these steps to initiate a repair:

1. Ensure OneNote is closed.
2. Access Windows Settings.
3. Navigate to Apps > Installed apps or Apps > Apps & features, depending on your version of Windows.
4. Search for Microsoft OneNote.
5. Select OneNote and click on Modify (in Windows 11, this will appear after you click the three dots).
6. Click Yes in the User Account Control prompt.
7. Choose the Online Repair option and click Repair.

7] Uninstall and Reinstall OneNote

If none of the previous methods resolve the issue, consider uninstalling and reinstalling Microsoft OneNote. If you installed OneNote through the Microsoft Store, you can uninstall it as a standalone app via Settings; otherwise, you may need to remove the entire Office suite before reinstalling it.

You can utilize the Microsoft SaRA tool for uninstalling Microsoft Office. Ensure you have the activation key before starting the uninstallation, as you will need it for reactivating your license after the reinstall.

We hope these solutions assist you!
