Question details
The user is experiencing an issue where handwritten pen strokes in OneNote vanish automatically during the synchronization process across devices.

- Product
- Microsoft OneNote
- Device & OS
- Windows PC and Android Tablet
- Scenario
- Synchronizing handwritten notes automatically between an Android tablet and a Windows computer using a Microsoft 365 enterprise work account.
- Observed behavior
- Pen strokes intermittently disappear during synchronization on the Microsoft 365 work account, whereas personal accounts on the same devices sync flawlessly.
Ensure that your internet connection is stable on both your Android tablet and Windows computer, and manually back up any unsynced handwritten notes by exporting the page as a PDF before beginning the troubleshooting process.
Verify Notes on the Web and Re-sync the Notebook
Checking the web version of OneNote helps determine if the sync failure is local to the device application or related to the cloud storage.
By forcing a manual refresh from the cloud, you can resolve temporary conflicts between the local cache and the server version of your notebook.
Open a web browser, log into your Microsoft 365 work account, and open the affected notebook to see if the handwritten strokes appear online.
On your Windows PC desktop application, right-click the name of the notebook experiencing issues and select 'Close This Notebook'.
In OneNote for the Web, click the 'Open in Desktop App' button to force a fresh synchronization of the notebook back to your local device.

Repair or Update the OneNote Desktop App
Corrupted application files or outdated software versions can cause synchronization conflicts and result in missing ink strokes.
Check Tenant Policies and Contact IT Support
Because the sync failure only affects the managed work account, enterprise device management policies might be interfering with background data transfers.

Frequently Asked Questions
Why do my handwritten notes disappear only on my work account?
Enterprise accounts are often subject to strict tenant policies, Intune compliance rules, or Company Portal restrictions. These policies can sometimes interrupt or throttle background synchronization, causing ink strokes to fail to upload, whereas personal accounts do not have these restrictions.
Can I recover the OneNote pen strokes that disappeared?
If the strokes never synced to OneNote for the Web, they might be lost. However, you can check the 'View' > 'Deleted Notes' section or look for local backup files by navigating to 'File' > 'Info' > 'Open Backups' in the desktop application.
Does updating the Android OneNote app fix sync issues?
Yes, ensuring that both your Android OneNote application and the Windows desktop client are on the latest versions minimizes compatibility bugs that often lead to synchronization drops and missing handwritten inputs.
