OneDrive Sync Pending Stuck — Files Not Uploading or Downloading

Errorapplication

Overview

Fix OneDrive sync stuck in pending state where files show a sync icon but never upload or download, causing outdated files across devices.

Key Details

  • OneDrive sync pending means files are queued for upload or download but the sync process is stalled
  • Files show a blue circular arrow icon indicating they are waiting to sync
  • The issue can affect individual files, folders, or the entire OneDrive sync client
  • OneDrive has file size limits (250GB per file) and path length limits (400 characters total path)
  • Sync conflicts occur when the same file is modified on multiple devices simultaneously

Common Causes

  • File name contains characters not supported by OneDrive (# % & { } \ < > * ? / ! ' " : @ + ` | =)
  • File path exceeds 400 characters total (including OneDrive folder path)
  • OneDrive storage quota exceeded — no space to upload new files
  • Sync client corrupted or stuck in a bad state requiring reset

Steps

  1. 1Check OneDrive status: click the OneDrive icon in system tray > look for error messages or paused sync
  2. 2Rename files with unsupported characters and shorten file paths that exceed 400 characters
  3. 3Check storage: click OneDrive icon > Settings > Account > verify available storage space
  4. 4Reset OneDrive sync: press Win+R, type %localappdata%\Microsoft\OneDrive\onedrive.exe /reset, press Enter
  5. 5If reset does not work: unlink and relink the account in OneDrive Settings > Account > Unlink this PC

Frequently Asked Questions

No. Resetting OneDrive only resets the sync client configuration. Your files remain in the cloud and on your local machine. After reset, OneDrive will re-sync and may take time to re-index files.
