How to Fix OneNote Older-Format Sync Error 0xE40200C4
Question details
Users are unable to synchronize large OneNote notebooks to the cloud because certain sections are flagged as being created in an older, incompatible format.
- Product
- Microsoft OneNote
- Device & OS
- Windows, Android, Web
- Scenario
- Synchronizing existing notebooks across multiple devices and cloud platforms like OneDrive or SharePoint.
- Observed behavior
- Synchronization fails across all connected devices, returning error code 0xE40200C4 with a message stating that a section was created in an older version and is incompatible with the cloud notebook.
Ensure you have a stable internet connection and back up your current OneNote notebooks locally before attempting to move or copy any notebook sections.
Move Content to a Newly Created Cloud Notebook
Transferring your notes from the older-format sections into a newly created, modern notebook structure bypasses the format incompatibility and restores synchronization.
Error 0xE40200C4 typically occurs when older OneNote section files (such as those from OneNote 2003 or 2007) are uploaded directly to OneDrive or SharePoint. Modern cloud synchronization requires the updated OneNote file structure.
To resolve this, you must manually create a new notebook in the modern format and copy the data over. Do not move the original files using Windows File Explorer, as this will not update the internal section formatting.
Open the OneNote desktop application. Go to 'File' > 'New' and create a brand-new notebook. Ensure you choose OneDrive or SharePoint as the save location.
Navigate to the existing notebook that is currently failing to synchronize and displaying the 0xE40200C4 error.
Right-click on the section tabs you wish to transfer. Select 'Move or Copy', then choose the newly created notebook as your destination and click 'Copy'.
Once all sections are copied, right-click the new notebook name and select 'Sync This Notebook Now' to ensure the files properly upload to the cloud.
Switch to WPS Office for Seamless Cross-Device Note-taking
If you frequently encounter formatting limitations and synchronization errors with Microsoft products, consider switching to WPS Office. It provides a lightweight, free, and highly compatible alternative with built-in cloud storage for reliable cross-device access.
Frequently Asked Questions
What does error code 0xE40200C4 mean?
This error indicates that one or more sections in your notebook are using an outdated file format (like OneNote 2003 or 2007) that is no longer supported for cloud synchronization by OneDrive or SharePoint Online.
Can I automatically upgrade the notebook format instead of copying sections?
Sometimes you can upgrade the format by opening the OneNote desktop app, going to File > Info > Settings > Properties, and clicking 'Convert to 2010-2016'. However, if the notebook is already stuck in a sync error loop, manually copying the sections to a new notebook is often the most reliable solution.
Why am I seeing this error on Android if the notebook was created on Windows?
The synchronization error originates from the cloud server rejecting the outdated file format. When your Android device attempts to fetch or sync changes with the cloud server, it encounters the same server-side rejection, causing the error to display across all your connected devices.
