How to Fix OneDrive File Upload Failures and Sync Problems
Question details
Users are experiencing issues where files fail to upload to OneDrive, resulting in synchronization problems across multiple devices, often accompanied by error status icons.
- Product
- Microsoft OneDrive
- Device & OS
- not provided
- Scenario
- Attempting to upload documents and keep files synchronized across multiple desktop and mobile devices.
- Observed behavior
- Files do not upload successfully, multiple devices fail to synchronize the latest changes, and small status icons appear beside the affected files indicating an error.
Ensure you have a stable internet connection and verify that you have sufficient cloud storage space available in your Microsoft account before attempting to troubleshoot sync issues.
Identify Status Icons and Test Web Upload
Determine the exact cause of the sync failure by cross-referencing the file's status icon and testing the upload via the web browser.
OneDrive uses various small icons on files to indicate their sync status. Identifying this icon can pinpoint the exact cause of the failure.
Look at the small icon next to the affected file and compare it against Microsoft's official OneDrive icon guide to identify the specific error (e.g., storage full, invalid characters).
Log in to OneDrive on a web browser and try uploading the same file directly. If it uploads successfully on the web but fails on your computer, the issue is isolated to your local desktop application.
Confirm whether you are using a Personal or a Work/School account, as business accounts may have specific IT restrictions blocking certain file types or sizes.
Unlink and Relink Your OneDrive Account
Refreshing the connection between your device and the OneDrive server can resolve persistent synchronization glitches.
Reset the OneDrive Client
Resetting the application clears the local sync cache and often fixes persistent upload failures.

Frequently Asked Questions
Why does my OneDrive file have a red circle with a cross icon?
A red circle with a white cross means that a file or folder cannot be synced. This usually happens if the file is too large, your cloud storage is full, or the file name contains invalid characters.
Will unlinking my OneDrive delete my locally stored files?
No, unlinking your PC from OneDrive will not delete any files. Your data remains safely stored in your cloud account and locally on your device's hard drive.
How do I know if the sync issue is device-specific or an account problem?
You can isolate the issue by trying to upload the file via the OneDrive web portal. If the file uploads successfully on the web but fails on the desktop application, the issue is likely specific to your desktop client.
Can I use WPS Office to edit files stored in my local OneDrive folder?
Yes, you can easily open, edit, and save documents stored in your local OneDrive directory using WPS Office, while retaining full compatibility with standard Microsoft Office formats.
