OneDrive is a popular cloud storage service integrated into Windows 11. However, sometimes users experience an upload blocked error, which stops files from syncing properly. This can be frustrating, especially if you rely on OneDrive for backup or sharing.
Fortunately, there are several straightforward ways to fix this problem. Many solutions involve simple checks and settings adjustments. This guide will walk you through step-by-step solutions to resolve the OneDrive upload blocked error on Windows 11.
By following these methods in order, you can identify and fix the issue without needing advanced technical skills. Let’s get started.
These instructions are designed to be clear and easy, even if you are not familiar with Windows troubleshooting.
Quick Note: Prerequisites and Basic Checks
Before diving into troubleshooting, make sure of the following:
- Internet Connection: Ensure your PC has a stable internet connection. OneDrive needs internet to upload files.
- OneDrive Account: Confirm you are signed into OneDrive with the correct Microsoft account.
- Storage Space: Check that your OneDrive cloud storage is not full.
- File Size and Type: Verify that the files you are uploading do not exceed OneDrive’s size limit and are supported file types.
Step 1: Restart OneDrive
Sometimes, the simplest fix is restarting the OneDrive app. This refreshes its connection and can clear temporary glitches.
- Click the OneDrive icon in the system tray (bottom-right corner of the screen).
- If the icon is hidden, click the upward arrow to find it.
- Right-click the OneDrive icon and select Close OneDrive.
- Wait a few seconds, then open OneDrive again by searching for OneDrive in the Start menu and clicking the app.
After restarting, try uploading files again and see if the error persists.
Step 2: Check File Path and File Name
OneDrive has limitations on file paths and names. If the file path is too long or contains special characters, uploads may fail.
- Ensure the full file path (including folders) is less than 400 characters.
- Avoid using special characters like
: * ? " < > |in file or folder names. - Try renaming the file or moving it to a folder closer to the root directory (like C:UsersYourNameDocuments).
Correcting file names or paths often resolves upload blocks caused by naming restrictions.
Step 3: Pause and Resume Syncing
Pausing and resuming syncing can reset the upload process and fix stuck files.
- Click the OneDrive icon in the system tray.
- Select Help & Settings (gear icon).
- Click Pause syncing and choose a time interval (e.g., 2 hours).
- Wait a minute, then go back to Help & Settings and click Resume syncing.
This action refreshes OneDrive’s syncing engine and can unblock uploads.
Step 4: Check for Windows and OneDrive Updates
Outdated software can cause compatibility issues. Keeping Windows and OneDrive updated ensures you have the latest fixes.
- Open Settings by pressing
Win + I. - Go to Windows Update and click Check for updates. Install any available updates.
- To update OneDrive, open the app, click Help & Settings, then Settings.
- Go to the About tab and click Version number; this will check for OneDrive updates.
After updating, restart your PC and try uploading again.
Step 5: Reset OneDrive
If the problem continues, resetting OneDrive can resolve deeper issues without deleting your files.
- Press
Win + Rto open the Run dialog. - Type the following command and press Enter:
%localappdata%MicrosoftOneDriveonedrive.exe /reset
This will reset OneDrive settings and re-sync all files. It may take some time depending on your data size.
If the OneDrive icon does not reappear after a few minutes, open the Run dialog again and enter:
%localappdata%MicrosoftOneDriveonedrive.exe
Once reset is complete, check if uploads work properly.
Step 6: Check Storage Sense or Disk Space
Windows 11’s Storage Sense feature can automatically free up disk space, sometimes affecting OneDrive folders.
- Open Settings and go to System > Storage.
- Look for Storage Sense and click to configure.
- Make sure it is not deleting OneDrive files or temporary files needed for syncing.
- Also, check local disk space on your PC’s drive to ensure there is enough room for syncing files.
Alternative Methods and Advanced Options
If the above steps do not help, try these additional solutions:
- Unlink and Relink OneDrive Account: Go to OneDrive settings, click Account, then Unlink this PC. Afterward, sign in again.
- Disable Proxy or VPN: Sometimes network proxies or VPNs interfere with OneDrive uploads. Temporarily disable them to test.
- Run Windows Troubleshooter: Open Settings > Update & Security > Troubleshoot > Additional troubleshooters, and run the Windows Store Apps troubleshooter.
- Check File Permissions: Ensure you have the necessary permissions to upload or modify files in the OneDrive folder.
