Fix Shared OneNote Notebook Not Opening in iPhone App
Question details
The user needs to resolve an issue where a shared OneNote notebook link opens in a web browser but does not provide an option to open in the OneNote iOS app.

- Product
- Microsoft OneNote
- Device & OS
- iOS / iPhone
- Scenario
- Sharing a OneNote notebook with an iPhone user.
- Observed behavior
- The shared notebook opens in the mobile web browser, but the option to open it directly in the OneNote mobile app is missing or unresponsive.
Ensure that the iPhone user has the latest version of the Microsoft OneNote app installed from the App Store and is logged in with a valid Microsoft account.
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.
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.
Ensure the permission is set to 'Anyone with the link can edit' or specifically invite the user's Microsoft account with edit permissions.
Copy the newly generated sharing link and send it to the iPhone user.
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.

Use a Different Browser or Recreate the Notebook
Bypass browser cache issues or corrupted notebook configurations by testing alternative browsers or copying the data to a fresh notebook.
Switch to WPS Office for Seamless Document Sharing
If you frequently encounter synchronization, permission, or sharing issues with Microsoft Office apps on mobile devices, consider trying WPS Office. It is a free, lightweight, and highly compatible alternative that makes collaborating on documents, spreadsheets, and presentations effortless across all devices, including iPhones.
- 1. Open WPS Office: Launch the WPS Office app on your device and open the document you wish to share.
- 2. Generate a sharing link: Tap the 'Share' button at the bottom or top of the screen and select 'Share as Link'.
- 3. Set permissions and send: Choose your preferred permission settings (View Only or Edit) and easily send the link via messaging apps or email directly to your contacts.

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.
