How to Fix OneNote Crashing on iPad When Editing and Syncing

Observed behavior: OneNote opens normally but crashes as soon as text is edited and synchronization begins. Reinstalling the app and restarting the iPad did not resolve the issue.

Before you start

Before proceeding, manually copy any recently typed, un-synced notes into another app like Apple Notes to prevent data loss, and ensure your iPad is connected to a stable Wi-Fi network.

Verify Updates and Isolate the Syncing Issue

Determine if the crash is caused by outdated software or a corrupted specific notebook by testing updates and web access.

App crashes during synchronization are often caused by conflicts between the local app cache and the cloud server, or specific corrupted sections within a notebook.

By isolating whether the crash happens on a single notebook or across the entire app, you can determine if the issue requires a simple notebook reset or advanced Microsoft Support intervention.

Check for iPadOS and App updates

Open the App Store to check for any pending OneNote updates. Then, navigate to Settings > General > Software Update on your iPad to ensure you are running the latest version of iPadOS 17.

Test OneNote for the Web

Open Safari or another web browser on your iPad, navigate to onenote.com, and log in. Try editing the same notebook to see if the web version functions normally without crashing.

Test a new notebook

Open the OneNote iPad app and create a brand new notebook. Type some text to trigger a sync. If the new notebook syncs perfectly, your original notebook data may be corrupted.

Contact Microsoft Support

If the app continues to crash across all notebooks even after updates, reach out to Microsoft Support. Be sure to provide them with your exact iPad model, OS version, and details of the crash.

Verify Updates and Isolate the Syncing Issue

Data Loss Warning: Do not sign out of your account or force-close the app repeatedly if you have un-synced data, as this can result in permanent loss of those specific notes.

Frequently Asked Questions

Why does OneNote crash only when synchronizing?

Sync crashes generally occur due to a corrupted notebook section, conflicting versions between the local device cache and the cloud, or background network connectivity issues disrupting the data handshake.

Will I lose un-synced notes if I delete and reinstall OneNote?

Yes. Any notes that have not been successfully synchronized to OneDrive will be permanently lost if you delete the app. You should always copy un-synced content to another text app before reinstalling.

How do I force sync a specific notebook in OneNote for iPad?

You can force a synchronization by pulling down on the notebook or page list, or by tapping the sync status icon (a cloud with a sync arrow) located next to the notebook's name in the left sidebar.
