Solution 1Recommended

Contact Microsoft Support for Backend Investigation

Since this specific error appearing across all devices typically indicates a backend server issue, reaching out to Microsoft Support is the most effective solution.

When reinstalling or relinking OneDrive does not resolve the 'This item might not exist' error on any device, the root cause is likely a synchronization or database issue on Microsoft's servers. Users have reported that opening a dedicated support ticket is required to prompt Microsoft engineers to fix the backend connection for the affected account.

1
Log into Microsoft Support

Navigate to the official Microsoft Support website and log in using the Microsoft account associated with your affected personal OneDrive.

2
Open a support request

Search for 'OneDrive file access issue' in the support search bar and select the option to contact support or open a new service ticket.

3
Provide error details

Clearly explain that you are receiving the 'This item might not exist' error on all devices including the web interface, and mention that standard troubleshooting has already been attempted.

4
Wait for backend resolution

Microsoft's technical team will investigate your account. Once the backend issue is resolved, your files will automatically become accessible again.

Avoid modifying files: Do not repeatedly try to delete, move, or rename the affected files while waiting for support, as this might complicate the recovery process.

Frequently Asked Questions

Why does OneDrive say 'This item might not exist' when I own the file?

This error usually occurs when the file has been moved, deleted, or when there is a synchronization failure between your local device and Microsoft's backend servers. If it happens on all devices simultaneously, it is likely a server-side account issue.

Will reinstalling the OneDrive desktop app fix this error?

Reinstalling or unlinking your PC from OneDrive can fix local sync glitches. However, if you experience the exact same error on the OneDrive website, reinstalling the local app will not resolve the problem.

Should I delete and re-upload the files causing the error?

No. It is strongly advised not to delete or move files that display this error if it stems from a backend issue, as doing so might result in permanent data loss before Microsoft Support can restore access.

How long does it take for Microsoft Support to fix OneDrive backend issues?

Based on user reports, backend access issues typically take a few days to resolve after a support ticket is officially opened and escalated to the engineering team.
