Enable Optional Diagnostic Data in Privacy Settings

Adjusting the privacy settings to allow optional diagnostic data can restore the communication between OneNote and Word on iOS, allowing links to open properly.

Due to app sandboxing and privacy configurations on iOS, OneNote may sometimes fail to hand off document links to the Word app. Enabling optional diagnostic data has been widely reported by users to resolve this communication bug.

Open OneNote Settings

Launch the OneNote app on your iPhone or iPad and tap on your profile picture or the settings gear icon to access the menu.

Access Privacy Settings

Scroll down and select "Privacy Settings" from the list of options.

Enable Diagnostic Data

Locate the "Optional Diagnostic Data" option and toggle the switch to turn it on.

Restart OneNote

Force close the OneNote app by swiping it away from your recent apps screen, then reopen it and try tapping the Word document link again.

Restart Required: The privacy setting changes will not take effect until the app is completely restarted.

Frequently Asked Questions

Why do the Word links work on Windows 11 but not on my iPhone?

Windows operating systems have deep, built-in integrations between Office applications. On iOS, apps operate in 'sandboxes' for security reasons, meaning they have stricter barriers when passing data or links to one another. Enabling diagnostic data helps bridge this gap.

Will turning on optional diagnostic data share my personal document contents?

No. Microsoft's optional diagnostic data only sends app performance, hardware configuration, and usage statistics to help developers troubleshoot bugs. It does not scan or share the text within your private documents.

What should I do if the link still says it is invalid after I restart the app?

If the error persists, try signing out of your Microsoft account in both OneNote and Word, then sign back in. Additionally, verify via a web browser that the Word document hasn't been moved or deleted from its original location on OneDrive or SharePoint.
