Verify Notebook Ownership and Sharing Permissions

Ensure you are the owner of the notebook and resend the sharing link with the correct editing permissions to trigger the app prompt.

Sometimes the 'Open in App' option fails to appear because the recipient does not have the proper permissions, or the original sharing link was generated with restricted viewing access. Resetting the permissions can resolve this.

1
Open sharing settings

Open OneNote on your desktop or web browser and navigate to the notebook you want to share. Click on the 'Share' button in the top right corner.

2
Adjust permissions

Ensure the permission is set to 'Anyone with the link can edit' or specifically invite the user's Microsoft account with edit permissions.

3
Resend the link

Copy the newly generated sharing link and send it to the iPhone user.

4
Open on iPhone

Ask the recipient to open the link on their iPhone. The browser should now properly authenticate the permissions and display the 'Open in App' button.

Account Requirement: While users can view notebooks in a browser without an account, editing inside the OneNote iPhone app requires them to sign in with a Microsoft account.

Frequently Asked Questions

Why does my shared OneNote link only open in Safari on my iPhone?

This usually happens if the OneNote app is not installed, the user is not signed in properly, or Safari is blocking the prompt to open external applications. Try clearing the browser cache, tapping the 'Open in App' banner at the top of the webpage, or opening the link in another browser like Chrome.

Can an iPhone user edit a OneNote notebook without a Microsoft account?

If the sharing link is set to 'Anyone with the link can edit', they can edit it in the web browser anonymously. However, using the actual OneNote mobile app on an iPhone requires the user to sign in with a free Microsoft account.

How do I force a OneNote link to open directly in the iOS app?

When the notebook opens in the mobile web browser, look for a banner at the top of the screen or a button in the top ribbon menu that says 'Open in App'. Tapping this will manually redirect you to the OneNote app. Ensure you are not browsing in Private/Incognito mode, as this can block app redirects.
