How to Fix OneDrive My Files 404 File Not Found Error
Question details
Users are encountering a 404 File Not Found error when attempting to open their stored documents directly from the My Files tab in OneDrive.
- Product
- OneDrive
- Device & OS
- Windows 10 PC, iOS
- Scenario
- Accessing and opening files through the OneDrive interface after a recent update that introduced the Home tab.
- Observed behavior
- Opening files from the 'My Files' tab returns a 404 error. However, the same files can be successfully downloaded, deleted, uploaded, or opened normally via the 'Home' tab or the iOS mobile application.
Verify your internet connection and ensure that you can temporarily access your files from a mobile device or another computer to avoid losing unsaved progress on ongoing projects.
Use Alternative Access Methods
Since the error is isolated to the My Files tab, accessing your documents from other locations within the OneDrive ecosystem serves as an immediate workaround.
This is a known bug that affects the web and desktop view for personal accounts on Windows 10 PCs. Bypassing the affected directory allows you to keep working while waiting for a system update.
Navigate to the OneDrive interface and click on the 'Home' tab on the left sidebar instead of 'My Files' to locate and open your recent documents.
Go to the 'My Files' tab, right-click (or select) the file returning the 404 error, and click 'Download'. Open the local copy on your PC.
Launch the OneDrive application on your smartphone (such as an iPhone) where the 404 error does not trigger, and view or share your files from there.
Update and Refresh Your OneDrive Client
The OneDrive and Office engineering teams have investigated and resolved this known service issue for most users.
Report Persistent Errors to Microsoft
If you are still experiencing the 404 error after the official fix was deployed, use the mobile app's feedback tool to notify the development team.

Frequently Asked Questions
Why does OneDrive show a 404 File Not Found error in the My Files tab?
This specific error was caused by a known service bug introduced during a OneDrive update that added the Home tab. It temporarily broke the file path links exclusively inside the 'My Files' directory for personal accounts on Windows PCs.
Are my files deleted if I get the 404 error on OneDrive?
No, your files are completely safe and have not been deleted. The error only prevents the file from opening directly in the browser or desktop app from that specific tab. You can still download the files or view them via the OneDrive mobile app.
How long does it take for the OneDrive development team to fix the 404 error?
The Microsoft engineering team has already investigated and released a patch for this bug. If you are still seeing the error, try logging out, clearing your browser cache, and logging back in to ensure your account syncs with the latest server updates.
