How to Stop OneNote from Closing Automatically on iPhone or iPad
Question details
Users are experiencing an issue where the OneNote application repeatedly closes or crashes on iOS devices.
- Product
- Microsoft OneNote
- Device & OS
- iOS / iPadOS
- Scenario
- Opening or using OneNote on a mobile Apple device for note-taking.
- Observed behavior
- The OneNote app repeatedly closes automatically and unexpectedly, preventing normal usage and potentially disrupting workflows.
Before proceeding with any resets or uninstalls, verify that your recent notes have successfully synced to OneDrive by checking from a web browser to prevent accidental data loss.
Reset OneNote Sign-In Credentials via iOS Settings
Clearing your sign-in credentials often resolves underlying authentication conflicts that force the app to close unexpectedly.
Corrupted sign-in tokens are a common reason for Microsoft Office apps to crash on iOS. Resetting the credentials forces the app to refresh its authentication state without deleting the app itself.
Swipe up from the bottom of your screen (or double-click the Home button) and swipe the OneNote preview up to close it completely.
Navigate to the home screen and tap on the 'Settings' app.
Scroll down through your list of installed apps and tap on 'OneNote'.
Tap on 'Reset OneNote', then toggle on the switch for 'Delete Sign-In Credentials'.
Return to your home screen, launch the OneNote app, and sign in again with your Microsoft account.
Update iOS and the OneNote App
Running outdated software can lead to compatibility issues and recurring app crashes.
Uninstall and Reinstall OneNote
A fresh installation replaces corrupted application files that may be triggering the automatic closures.
Try WPS Office for Stable Document Editing on iOS
If Microsoft Office applications continue to crash on your iPhone or iPad, consider switching to WPS Office. It provides a lightweight, highly stable environment for all your document, spreadsheet, and presentation needs without unexpected closures.
- 1. Download the App: Search for WPS Office in the Apple App Store and download it to your iPhone or iPad.
- 2. Open Your Files: Launch WPS Office and connect your cloud storage or open local documents directly.
- 3. Edit Without Crashing: Enjoy smooth, stable editing and viewing of your Office files without unexpected app closures.
Frequently Asked Questions
Why does OneNote keep crashing on my iPad?
Crashes are typically caused by outdated app versions, corrupted sign-in credentials, low device storage, or syncing conflicts with excessively large notebooks.
Will resetting OneNote delete my notebooks?
Resetting sign-in credentials will not delete notebooks that have already been saved and synced to OneDrive. However, any recent notes that failed to sync to the cloud beforehand may be lost.
Does low device storage cause apps to close automatically?
Yes, if your iPhone or iPad is running out of storage, apps like OneNote may fail to allocate necessary memory for background caching and will close unexpectedly. You can check your available space via Settings > General > iPhone/iPad Storage.
What should I do if other Office apps are also crashing on my iPhone?
If Microsoft Word or Excel are also closing automatically, the issue is likely related to a system-wide iOS update compatibility or a shared Microsoft authentication token. Updating your iOS software and resetting credentials across the apps usually resolves this.
