- Device & OS
- not provided
- Scenario
- Opening hyperlinks in a notebook that redirect to external applications, custom scripts, or trusted local protocols.
- Observed behavior
- OneNote displays a persistent security warning prompt every time the user clicks a hyperlink to an external protocol.
Close all active Microsoft Office applications and verify that the target external protocol or application is from a verified, trusted source before adjusting security policies.
Disable Hyperlink Warnings via Registry Editor
Modify the Windows Registry to globally disable Office hyperlink security warnings or add specific protocols to the trusted list.
Disabling hyperlink warnings can expose your computer to unsafe applications. Proceed only if you fully trust the links you are working with.
For managed enterprise environments, an administrator may need to configure the trusted protocol policy.
Press the Windows key + R to open the Run dialog box. Type 'regedit' and press Enter. Click 'Yes' if prompted by User Account Control.
Navigate to the following path: HKEY_CURRENT_USER\Software\Microsoft\Office\<Your_Office_Version>\Common\Security. (Replace <Your_Office_Version> with your version number, such as 16.0 for Office 2016/365).
Right-click on the Security folder, select 'New', and then click 'DWORD (32-bit) Value'. Name the new value 'DisableHyperlinkWarning'.
Double-click 'DisableHyperlinkWarning', change the Value data from 0 to 1, and click OK. Restart your computer for the changes to take effect.
Configure Trusted Sites in Internet Options
Add the target website or network path to your trusted zones in Windows Internet Options, which Microsoft Office inherits for security checks.

Frequently Asked Questions
Why does OneNote show a security warning when opening links?
Microsoft Office applications, including OneNote, have built-in security features designed to protect your device from malicious scripts or executables disguised as hyperlinks. By default, opening an unfamiliar protocol triggers a warning.
Can I disable the warning for specific custom protocols only?
Yes. Instead of disabling the warning globally, you can add specific trusted protocols to the Windows Registry under HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\<Version>\Common\Security\Trusted Protocols.
Is it safe to disable Microsoft Office hyperlink warnings?
Disabling these warnings removes a layer of protection against potentially unsafe applications. It is only recommended if you operate in a secure environment and strictly control the external links and protocols you interact with.
