Hello Jaekwon,
Thank you for reaching out to the Microsoft Community and I'll be glad to assist you today.
I understand that you are having trouble syncing OneDrive. To better assist you, we would like to know the following information:
- Could you please post the screenshot of the OneDrive icon located in the taskbar?
- Did you check if your OneDrive storage has enough space to sync or upload files?
- May I please know the version or edition of the Windows operating system installed on your computer?
(To find the version, type winver in the search bar on the taskbar and click enter)
Meanwhile, you could try these troubleshooting steps below to fix the OneDrive sync issue and check if it helps.
- Make sure you have enough storage space in your OneDrive account.
a. Go to https://onedrive.live.com/?v=managestorage and sign in with your Microsoft account.
b. Ensure you have enough storage space on your account.
- Reset OneDrive:
Resetting Microsoft OneDrive can sometimes resolve sync issues and resets all OneDrive settings. OneDrive will perform a full sync after the reset.
You can locate the command lines to reset OneDrive on the link below.

- Since you have already re-installed OneDrive and there is still sync issues,
• Check for the latest Windows updates - Go to Settings > Windows updates > Check for updates and install the latest Windows updates.
• If your PC is up-to-date, try reinstalling your current version of Windows from the system recovery settings.
• Go to Settings > System > Recovery > Reset this PC (Select Reinstall now where it says Fix problems using Windows update)
Once completed, unlink your account from OneDrive settings and link again. This should restart the sync and it should work normally.
- Try connecting your device to a different network.
If you are experiencing issues syncing your files from a specific wi-fi network, try connecting your device to a mobile hotspot network and see if it works properly. So that we can determine if the issue is with the networks rather than OneDrive.
I hope this information helps. If you have any questions, please let me know and I will be happy to help you further.
Best regards,
