Why Does This Error Occur?
Teams relies on OneDrive to store and share files in chats. If OneDrive is inaccessible, frozen, or misconfigured, file uploads fail. Common triggers include:
• OneDrive Storage Issues: Exceeding storage limits or account suspension.
• Sync Errors: Corrupted cache or outdated Teams app.
• Permissions: Restricted access to OneDrive folders or administrative settings.
Step-by-Step Solutions
1. Check OneDrive Status
• Log into OneDrive via Browser: Visit OneDrive. If you see a "Your account is frozen" message, click Unfreeze. Note: Full restoration may take 24 hours, but file uploads in Teams should resume immediately.
• Verify Storage Limits: Ensure your OneDrive storage isn’t full. Delete unnecessary files or upgrade your plan if needed.
2. Clear Teams Cache
• On Desktop:
o Close Teams.
o Press Win + R, type %appdata%\Microsoft\Teams, and delete all files in the folder.
o Restart Teams.
3. Update Microsoft Teams
• Open Teams > Click your profile icon > Check for Updates. Install the latest version to resolve compatibility issues 7.
4. Adjust OneDrive Folder Name (Admin-Only)
• For Organizations: If the default "Documents" folder was renamed, admins must revert it to "Documents" via the Microsoft 365 Admin Center to fix upload errors.
5. Restart Teams or Your Device
• A simple restart often resolves temporary glitches.
6. Contact IT Support or Microsoft
• If the issue persists, submit a support request with Teams logs via Help > Report a Problem.
