Fix OneNote for Windows 10 Access Denied Error for Local Links
Question details
Users encounter an 'Access Denied' error when attempting to open hyperlinks to local files, network shares, or localhost resources within OneNote.
- Product
- Microsoft OneNote
- Device & OS
- Windows 10
- Scenario
- Clicking hyperlinks embedded in notes that point to local documents or network drives.
- Observed behavior
- The application displays an 'Access Denied' error and blocks the file from opening, despite the user having proper system permissions. The same links function correctly in the standard OneNote desktop version.
Verify that the local file or network share actually exists at the specified path and that your Windows user account has permission to read it through File Explorer.
Switch to the OneNote Desktop Application
Bypass the UWP sandbox restrictions by using the standard OneNote desktop client instead of the Windows 10 app.
OneNote for Windows 10 is a Universal Windows Platform (UWP) application. For security reasons, Windows UWP apps run in an isolated sandboxed environment that heavily restricts them from directly opening local files, localhost URLs, or network shares. Microsoft's standard OneNote Desktop application (Win32) does not have these restrictions.
Visit the Microsoft Store or the official Microsoft Office website to download the standard OneNote Desktop application (sometimes labeled as OneNote 2016 or just OneNote).
Launch the newly installed OneNote desktop application and sign in with the same Microsoft account to automatically sync your existing notebooks.
Navigate to the page containing your local or network links and click them. They will now open properly in their default applications without triggering the Access Denied error.
Update OneNote for Windows 10
Ensure you have the latest app updates from the Microsoft Store, though switching to the desktop app remains the definitive fix.
Experience Unrestricted Document Management with WPS Office
If you are frustrated by app limitations and sandbox restrictions in Microsoft Office apps, consider switching to WPS Office. It provides a lightweight, unified suite for your Word, Excel, and PowerPoint needs without restrictive local file blocking, ensuring seamless access to all your local and network files.
Frequently Asked Questions
Why does OneNote for Windows 10 restrict local files?
It is built as a Universal Windows Platform (UWP) app. UWP apps run in an isolated sandbox designed for security, which inherently prevents them from executing local files or accessing unapproved network paths directly.
Can I disable the security sandbox in OneNote for Windows 10?
No, the UWP sandbox is a core security feature of the Windows 10 operating system and cannot be bypassed for specific apps like OneNote. The official workaround is using the traditional desktop version.
Are OneNote Desktop and OneNote for Windows 10 the same?
No. OneNote for Windows 10 is the pre-installed UWP application, while OneNote Desktop (often included with Microsoft 365 or Office 2021) is a traditional Win32 application with full system and file access.
Will I lose my notes if I switch to OneNote Desktop?
No. As long as your notes are successfully synced to OneDrive or SharePoint, they will automatically populate in the Desktop application as soon as you sign in with the same Microsoft account.
