Question details

The user is experiencing persistent syncing failures, crashes, and freezing when attempting to use Microsoft OneNote on iOS devices.

Product: Microsoft OneNote
Device & OS: iOS (iPhone or iPad)
Scenario: Trying to synchronize notes across devices or open the application for regular note-taking.

Solution 1Recommended

Reset OneNote App Settings

Access iOS Settings

Navigate to the home screen of your iPhone or iPad and open the native Settings application.

Reset the app

Scroll down the Settings menu to find 'OneNote' in your list of installed apps. Tap it, select 'Reset OneNote', and toggle on the option to 'Delete Login Credentials'.

Sign back in

Relaunch the OneNote application from your home screen and sign in with your Microsoft account to re-establish the connection and allow your notebooks to sync properly.

Restart Device and Reinstall OneNote

If resetting does not work, performing a clean installation ensures that corrupted local files are completely removed from your device.
