Solution 1Recommended

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.

1
Access OneNote for the Web

Open a web browser, log into your Microsoft 365 work account, and open the affected notebook to see if the handwritten strokes appear online.

2
Close the local notebook

On your Windows PC desktop application, right-click the name of the notebook experiencing issues and select 'Close This Notebook'.

3
Reopen from the cloud

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.

Verify Notes on the Web and Re-sync the Notebook
Avoid Data Loss: Do not close the notebook locally if there are un-synced changes or new strokes that only exist on your device, as closing it will permanently delete any data not yet saved to the cloud.

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.
