Question details

Users are unable to synchronize files via the OneDrive desktop application on Windows following a recent system or app update, despite mobile and web access working perfectly.

Product: Microsoft OneDrive
Device & OS: Windows
Scenario: Attempting to sync local files to the cloud using the OneDrive desktop client after installing a Windows update.
Observed behavior: The OneDrive desktop app fails to connect to the service and stops syncing files completely. Reinstalling older versions of OneDrive does not resolve the desktop issue, while web and mobile platforms remain unaffected.

Before you start

Verify your internet connection is stable and ensure you can still log into your OneDrive account via a web browser to confirm it is not a widespread account issue.

Solution 1Recommended

Reset the OneDrive Desktop Client

Resetting OneDrive clears its local configuration and forces a full sync, which can resolve connection issues caused by a corrupted update cache.

Resetting the app will disconnect all your current sync connections, but it will not lose any of your files or data. It simply rebuilds the synchronization state.

Open the Run dialog

Press the Windows key + R on your keyboard simultaneously to open the Run window.

Execute the reset command

Type '%localappdata%\Microsoft\OneDrive\onedrive.exe /reset' into the dialog box and click OK.

Restart OneDrive

If the OneDrive icon does not reappear in your system tray within a few minutes, open the Start menu, search for OneDrive, and launch it manually.

Command Variation: If you see a 'Windows cannot find...' error, try typing 'C:\Program Files\Microsoft OneDrive\onedrive.exe /reset' instead.

Solution 2

Check Microsoft Service Status and Update OneDrive

Ensure that the problem isn't on Microsoft's end and manually update your client to the latest supported version.

Frequently Asked Questions

Why does my OneDrive work on mobile but not on Windows?

This indicates the issue is isolated to the desktop application or its interaction with a recent Windows update, rather than an account ban or server-wide outage. The mobile and web versions use different connection protocols.

Will resetting OneDrive delete my local files?

No, resetting the OneDrive client only clears the application's configuration cache and restarts the syncing process. It does not delete your local files or the files stored in the cloud.

How do I find my current OneDrive build number?

Click the OneDrive cloud icon in your taskbar, click the gear icon to open Settings, navigate to the 'About' tab, and look for the version number listed under the 'About Microsoft OneDrive' section.

What should I do if downgrading OneDrive doesn't fix the syncing problem?

Downgrading is rarely effective because OneDrive forces automatic background updates. Instead, you should reset the app, ensure your firewall allows OneDrive connections, or contact Microsoft Support with your specific build number and error details.
