Reset Credentials and Reinstall the OneNote App

Clearing outdated or corrupted login tokens and reinstalling the app often resolves syncing and access errors on iOS devices.

Authentication glitches can cause OneNote on iOS to lose its connection to OneDrive, resulting in false 'deleted' or 'moved' errors. Resetting the app credentials forces the app to establish a fresh connection.

1
Verify Account and OneDrive

Open OneDrive on a web browser and confirm the shared notebook is still available. Ensure you are noting the exact Microsoft account used for access.

2
Reset App Credentials

Open your iPhone's 'Settings' app, scroll down, and tap on 'OneNote'. Under the 'Reset' section, tap 'Reset OneNote' and toggle on 'Delete Login Credentials'.

3
Force Quit OneNote

Swipe up from the bottom of your iPhone screen to open the app switcher, locate the OneNote app preview, and swipe it upward to force close it.

4
Reinstall the Application

Tap and hold the OneNote app icon on your home screen, select 'Remove App', and then 'Delete App'. Visit the App Store, download OneNote again, and sign in with the verified Microsoft account.

Reset Credentials and Reinstall the OneNote App
Check Sharing Permissions: If the issue persists after reinstalling, the notebook owner may need to revoke your sharing link and issue a new one to refresh your access rights.

Frequently Asked Questions

Why does OneNote say my shared notebook is deleted or moved?

This usually happens when the iPhone app's local cache is corrupted, login credentials have expired, or there's a temporary syncing glitch with OneDrive, even if the file is perfectly fine on the server.

How do I force sync a notebook in OneNote for iOS?

Open the OneNote app, go to your notebook list, and pull down from the top of the screen to force a manual sync. You can also tap the sync status icon next to the notebook's name.

Will I lose my notes if I delete and reinstall the OneNote app?

Any notes that have already been synced to OneDrive are safe and will reappear when you sign back in. However, un-synced offline notes residing only on your iPhone might be lost during a reinstall.
