Onedrive Upload Pending | Onedrive Server Too Busy

These errors indicate that your OneDrive app is having trouble communicating with the server to complete a task, typically an upload. The reasons behind each error are slightly different, and the solutions vary accordingly.

OneDrive “Upload Pending”

This message means your file is queued for upload but is waiting for a condition to be met before it can be sent to the server. This is usually a client-side issue.

Common Causes:

• No Internet Connection:

  • The most frequent cause. The app is waiting for a stable internet connection to begin the upload.

• Conflict with Another File:

  • Another user or process is making changes to the same file, causing a conflict.

• Invalid File Name or Path:

  • The file name or folder path contains unsupported characters (e.g., *, ?, |, <, >) or is too long.

• File is Too Large:

  • The file exceeds the maximum size limit for a single upload (currently 250 GB, but older versions or specific settings may have a lower limit).

• File is in Use:

  • The file is open in another program, and OneDrive cannot access it to sync.

How to Fix “Upload Pending”:

1. Check Your Internet Connection:

   • Ensure you are connected to a stable network. If you are on a metered network (like mobile data), OneDrive may be set to pause syncs to save data.

2. Pause and Resume Syncing:

   • Right-click the OneDrive cloud icon in your system tray and select Pause syncing. Wait a few minutes, then right-click the icon again and select Resume syncing. This can often jump-start the process.

3. Check for Invalid Characters:

   • Rename the file to remove any special characters or symbols and try again. Shorten the file path if it’s excessively long.

4. Close the File:

   • If the file is open, save your changes, close the file, and wait for OneDrive to sync.

5. Reinstall or Reset OneDrive:

   • If the issue persists, a complete reinstall or reset can fix corrupted sync data.
     • On Windows: Press the Windows Key + R, and in the Run dialog, type %localappdata%\Microsoft\OneDrive\onedrive.exe /reset and press Enter.

OneDrive “Server Too Busy”

This is a direct message from the OneDrive server. It means the server is overloaded and cannot accept any more requests at this time. This is almost always a server-side issue.

Common Causes:

• High Server Traffic:

  • A large number of users or processes (like a major migration) are making a high volume of requests, causing the server to throttle new ones.

• Excessive Requests:

  • You are uploading a very large number of files in a short period, which can cause the server to temporarily block you to prevent resource overload.

How to Fix “Server Too Busy”:

1. Wait and Try Again Later:

   • This is the most effective solution. The “Server Too Busy” message is temporary. Wait for a few hours (or until off-peak times) and try your upload again.

2. Check Microsoft’s Service Status:

   • Visit the Microsoft 365 Service Status page (you may need to be a business administrator to view this) to check for any reported outages or service incidents.

3. Reduce Upload Volume:

   • If you are uploading a massive number of files, try breaking the upload into smaller batches.
