Observed behavior

Before you start

Solution 1Recommended

Update the App and Re-authenticate Your Account

Resolve underlying app defects and sync failures by installing the latest version of OneNote and refreshing your account session.

Outdated app versions or expired authentication tokens are the most common reasons OneNote stops syncing or allowing new note creation. Refreshing your session usually clears these temporary software blocks.

1
Update OneNote

Open the App Store on your iPhone, search for 'OneNote', and tap the 'Update' button if a newer version is available.

2
Sign out of your account

Open the OneNote app, tap your profile picture or the Settings gear icon, and select your account name to sign out.

3
Sign back in

Restart the app and sign back into your Microsoft account to force a fresh synchronization of your notebooks.

Frequently Asked Questions

Will I lose my existing notes if I reinstall the OneNote app on my iPhone?

Yes, if you delete and reinstall the OneNote app, any notes that have not been successfully synchronized to OneDrive will be permanently deleted. Always check your sync status before uninstalling.

What happens when my OneNote notebook reaches the 2 GB limit?

Once a notebook hits the 2 GB size limit on OneDrive, it will stop syncing and the app will restrict you from creating new notes or adding new files within that specific notebook. You must create a new notebook to continue.

Why does OneNote show a 'working offline' error when I try to make a new note?

This error occurs when the app cannot connect to Microsoft's servers. It is usually caused by a poor internet connection, expired account credentials, or a temporary service outage. Signing out and back in typically resolves authentication-related offline errors.
