Solution 1Recommended

Reset the OneDrive Application

Resetting the OneDrive app clears its settings and forces a full synchronization, which can resolve lingering cache issues after a storage upgrade.

When you run out of storage and then upgrade, the desktop app may fail to recognize the new quota due to cached settings. Resetting the app forces it to reconnect and check the current storage limits.

1
Open the Run dialog

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

2
Execute the reset command

Type %localappdata%\Microsoft\OneDrive\onedrive.exe /reset and press Enter.

3
Wait for restart

The OneDrive icon in your system tray will disappear and then reappear after a minute or two. If it does not reappear, manually launch OneDrive from the Start menu.

Reset the OneDrive Application
No Data Loss: Resetting OneDrive only resets the app's configuration and restarts the sync process. It does not delete any of your locally stored files.

Frequently Asked Questions

Will resetting OneDrive delete the files on my computer?

No, resetting the OneDrive application only clears the local sync cache and resets the app's settings. It will initiate a full resync to check for file differences, but it will never delete your locally stored files.

Why are my OneDrive files showing a red X icon?

A red X icon indicates that a file or folder failed to synchronize. This is often caused by a full cloud storage quota, a lack of write permissions, unsupported characters in the file name, or a local network issue.

How long does it take for a OneDrive storage upgrade to take effect?

In most cases, a storage upgrade is applied to your Microsoft account immediately. However, it can sometimes take up to 24 hours for the new storage quota to be reflected across all your connected devices and sync applications.

What should I do if my files still won't sync after resetting?

If resetting OneDrive does not resolve the issue, ensure that your OneDrive application is updated to the latest version. You can also try uninstalling and reinstalling the OneDrive app entirely to fix deeper software corruption issues.
