Question details

The user needs to stop the OneNote app from crashing unexpectedly when pressing the Backspace or Delete keys, or at random intervals on their iPad.

How to Fix OneNote Crashing When Pressing Backspace or Delete on iPad

Product: Microsoft OneNote
Device & OS: iPadOS
Scenario: Typing, editing text, and managing notes within the OneNote application on an iPad.
Observed behavior: The OneNote app abruptly crashes and closes when the user presses the Backspace or Delete key. It also occasionally crashes randomly, even when both the app and iPadOS are fully updated.

Before you start

Log into OneNote on a web browser to manually verify that all your recent notebooks are fully synchronized to OneDrive, as resetting the iPad app will permanently delete any unsynced local data.

Solution 1Recommended

Reset OneNote and Clear App Data via iPad Settings

Use the built-in iOS settings to clear OneNote's temporary cache and reset login credentials, which often resolves input-related crash loops.

Since iPadOS does not offer a direct 'Clear Cache' button like Android devices, you must use the Reset feature found within the system settings. This will force the app to rebuild its local database and clear out corrupted temporary files that cause the backspace key to trigger a crash.

Open iPad Settings

Close OneNote completely. Open the standard iPad 'Settings' app and scroll down the left-hand panel until you find 'OneNote'.

Access Reset Options

Tap on 'OneNote', then look at the right-hand panel. Scroll down and tap on 'Reset OneNote'.

Clear Login Credentials

Toggle on the switch for 'Delete Login Credentials'. If you are absolutely certain all notebooks are synced, you can also toggle 'Delete All Notebooks' to clear corrupted local cache data.

Restart and Sign In

Force close the Settings app. Reopen OneNote, sign back into your Microsoft account, and let your notebooks sync from the cloud.

Data Loss Warning: Do not select 'Delete All Notebooks' unless you have confirmed via OneNote Web that your recent notes are safely stored in OneDrive.

Solution 2

Test Input with a Completely New Notebook

Isolate the issue to determine whether the crash is caused by a corrupted notebook file rather than the application itself.

Solution 3

Uninstall and Reinstall OneNote

Perform a clean installation of the OneNote application to ensure no damaged application packages are causing the backspace trigger failure.

Frequently Asked Questions

Why does my OneNote app crash specifically when I press Backspace?

This is a known glitch related to how OneNote handles text rendering and auto-syncing simultaneously on iPadOS. Corrupted temporary cache files or formatting inconsistencies in the specific notebook section can trigger a fatal error when the app attempts to delete characters.

How do I clear the OneNote cache on an iPad?

iPadOS does not have a direct 'Clear Cache' button. You must go to iPad Settings > OneNote > Reset OneNote, and toggle on 'Delete Login Credentials' or 'Delete All Notebooks'. Make sure your notebooks are synced to the cloud first, as this will erase local offline data.

Will reinstalling the OneNote app delete my notebooks?

If your notebooks are successfully synced to your OneDrive account, they will not be lost. However, any notes or changes that have not yet synced to the cloud will be permanently deleted when you uninstall the app.

How can I check if my OneNote notebooks are fully synced?

Open a web browser, go to onenote.com, and sign in with your Microsoft account. Open your notebooks there. If the recent changes you made on your iPad appear on the web version, your data is safely synced.
