Question details
The user needs to resolve synchronization errors in OneNote on Android devices, where notebooks sync properly on Windows and the web but fail to sync on Android.

- Product
- Microsoft OneNote
- Device & OS
- Android
- Scenario
- Syncing OneNote notebooks across multiple devices and platforms.
- Observed behavior
- Sync errors, including codes 0xE00001BB, 0xE000145C, and 0xE0001473, appear on Android phones and tablets, or synchronization takes an unusually long time, despite working correctly on the desktop application.
Ensure your Android device has a stable internet connection and copy any unsynced notes to a local text file to prevent data loss during troubleshooting.
Perform Basic Network and App Troubleshooting
Test your internet connection and eliminate conflicts from VPNs or firewall apps to ensure a clear path to the sync servers.
Network fluctuations, active VPNs, or third-party firewalls can block the OneNote app from reaching Microsoft's servers, triggering sync errors.
Try syncing your notebook using a different Wi-Fi network, mobile data, or a mobile hotspot to rule out local network restrictions.
Temporarily disconnect any active VPNs and uninstall or disable third-party firewall applications on your Android device.
Open the OneNote app on your Android device, navigate to the notebook list, and swipe down from the top of the screen to force a manual synchronization.
Go to your Android Settings > Apps > OneNote > Storage and tap 'Clear Cache'. If the issue persists, uninstall OneNote and reinstall it from the Google Play Store.

Create a New Notebook to Force Synchronization
Moving problem sections to a new notebook can often bypass corrupted sync states and large file timeouts.
Escalate to Microsoft 365 Administrator Support
If the issue persists across all networks and notebooks, the tenant backend may require investigation by Microsoft.
Try WPS Office for Seamless Cross-Device Note-Taking and Document Management
If you frequently encounter synchronization errors with Microsoft apps, consider switching to WPS Office. It provides a lightweight, highly compatible, and free alternative for viewing, editing, and syncing your essential documents across Windows, Android, iOS, and Mac without the heavy resource requirements.
- 1. Download WPS Office: Search for WPS Office in the Google Play Store and tap 'Install'.
- 2. Sign in to enable cloud sync: Open the app and sign in with your email or Google account to activate free cloud synchronization.
- 3. Access documents anywhere: Create or upload your documents to WPS Cloud to seamlessly access and edit them across your mobile and desktop devices.

Frequently Asked Questions
Why do I get OneNote error 0xE00001BB on Android?
This error typically occurs due to network connectivity issues, server timeouts, or conflicts with VPNs and third-party firewalls on your Android device blocking the connection to Microsoft servers.
Does OneNote sync automatically in the background on Android?
Yes, OneNote syncs automatically in the background. However, exceptionally large notebooks or poor internet connections can delay this process, which may require you to perform a manual sync by swiping down on the notebook list.
How do I fix sync errors if my OneNote notebook is too large?
If your notebook is too large and frequently times out during sync, try splitting it into smaller notebooks. You can do this on your desktop by creating a new notebook and copying a few sections over, which often resolves mobile syncing bottlenecks.
