Introduction
When OneDrive stops syncing, your files get stuck. Edits you made at home don’t show up at work. Documents you thought were backed up simply aren’t. Shared folders your team relies on fall quietly out of date.
OneDrive not syncing is one of the most common Windows 11 frustrations — and it has a handful of well-known causes: a glitchy sync process, a full storage quota, a dropped internet connection, or a corrupted cache. The good news is that most sync problems are quick to fix using free, built-in tools. Work through these 7 fixes in order and you’ll be back in sync within minutes — no reinstall, no paid software needed.
Quick Answer
To fix OneDrive not syncing on Windows 11, right-click the OneDrive cloud icon in your taskbar and select Quit OneDrive, then reopen it from the Start menu. If that doesn’t work, check your internet connection, verify your storage quota isn’t full (5 GB free / 1 TB with Microsoft 365), and reset OneDrive using the built-in reset command — all explained step by step below.
Why OneDrive Stops Syncing
Before jumping to fixes, it helps to know the usual suspects:
- Process glitch: The OneDrive app crashes silently and gets stuck in a broken state.
- Storage full: Your cloud quota is at 100% — nothing new can upload until you free space.
- No internet: OneDrive pauses automatically when your connection drops or is too slow.
- Sync paused: You (or Windows) paused syncing on a metered connection and forgot to resume it.
- Outdated software: Old versions of OneDrive or Windows 11 can have bugs that block sync.
- Sign-in error: Your Microsoft account session expired and OneDrive needs you to log back in.
| Symptom | Likely Cause |
|---|---|
| OneDrive icon missing or frozen in taskbar | Process glitch |
| Red “x” on the OneDrive icon | Storage full or sign-in error |
| Pause icon / “Syncing paused” message | Metered connection, low battery, or manual pause |
| “Sign in to sync” message | Account session expired |
| Other apps also lose internet access | Internet connection problem |
7 Fixes for OneDrive Not Syncing on Windows 11
Work through these in order — most people solve the problem within the first three steps.
Fix 1: Restart OneDrive
The simplest fix works surprisingly often. Restarting clears any stuck processes and forces OneDrive to reconnect from scratch.
- Find the OneDrive cloud icon in your taskbar (bottom-right, near the clock). If you don’t see it, click the up-arrow to reveal hidden icons.
- Right-click the icon and select Pause syncing, then Quit OneDrive.
- Press the Windows key, type OneDrive, and click the app to relaunch it.
- Watch the icon — spinning arrows mean it’s syncing again.
Pro tip: If the OneDrive icon is completely missing from your taskbar, open File Explorer, navigate to C:Program FilesMicrosoft OneDrive, and double-click OneDrive.exe to start it manually.
Fix 2: Check Your Internet Connection
OneDrive can’t sync without internet. If your connection is down or unstable, sync will stall indefinitely.
- Open a browser and try loading any website. If it fails, your internet — not OneDrive — is the problem.
- Run the Windows Network troubleshooter: go to Settings → System → Troubleshoot → Other troubleshooters → Internet Connections, then click Run.
- Once your connection is restored, OneDrive will resume automatically within about a minute.

Fix 3: Check Your OneDrive Storage Quota
If your OneDrive is full, no new files can upload. Microsoft gives every account 5 GB free; Microsoft 365 subscribers get 1 TB per person.
- Right-click the OneDrive icon in your taskbar.
- Click the gear icon (Settings), then select Account.
- Check the storage bar. If it’s at or near 100%, delete files at OneDrive.com or upgrade your plan before sync can resume.
If your local drive is also running low on space, see our guide on How to Free Up Disk Space on Windows 11 (Fast, Free, and Safe).
Fix 4: Pause and Resume Syncing
Sometimes sync gets stuck mid-transfer. Pausing and resuming restarts the upload queue without closing the app.
- Right-click the OneDrive icon in your taskbar.
- Select Pause syncing → 2 hours.
- Wait 10 seconds, then right-click again and select Resume syncing.
Fix 5: Sign Out and Sign Back In
If your Microsoft account session has expired, OneDrive quietly stops syncing. You may see a banner saying “Sign in to sync OneDrive files.”
- Right-click the OneDrive icon and go to Settings → Account.
- Click Unlink this PC and confirm.
- Reopen OneDrive from the Start menu and sign back in with your Microsoft account.
This is completely safe — your cloud files stay untouched. OneDrive simply re-scans your folders and resumes syncing.
Fix 6: Reset OneDrive
A full reset clears OneDrive’s local cache and connection settings without deleting any of your files. Use this for stubborn sync problems that simple restarts can’t fix.
- Press Windows + R to open the Run dialog.
- Type this command exactly and press Enter:
%localappdata%MicrosoftOneDriveonedrive.exe /reset - The OneDrive icon disappears for 1–2 minutes while the reset runs.
- If OneDrive doesn’t reopen automatically after 2 minutes, press Windows + R again, type
%localappdata%MicrosoftOneDriveonedrive.exe, and press Enter to relaunch it.
Troubleshooting tip: If the reset command shows a “file not found” error, try C:Program FilesMicrosoft OneDriveonedrive.exe /reset instead.
Fix 7: Update Windows and OneDrive
Outdated software is an easy-to-overlook cause of sync failures. Microsoft regularly patches OneDrive bugs through both Windows Update and the Microsoft Store.
- Go to Settings → Windows Update and click Check for updates. Install any available updates and restart your PC.
- Open the Microsoft Store, click the Library icon (bottom-left), and click Get updates to update OneDrive to the latest version.
If Windows Update itself won’t run, see our guide on How to Fix Windows Update Not Working on Windows 11.
Common Mistakes to Avoid
- Skipping the storage check first. A red “x” on the OneDrive icon almost always means your quota is full. Check your storage bar before trying anything else — it’s the most common cause and takes 30 seconds to rule out.
- Quitting OneDrive and forgetting to restart it. OneDrive only syncs while it’s running. If the cloud icon is missing from your taskbar, nothing is syncing. Reopen it from the Start menu.
- Syncing on a metered connection. Windows automatically pauses OneDrive on mobile hotspots and pay-per-MB connections to save data. To allow sync, go to Settings → Network & Internet → [your connection] → Properties and turn off Set as metered connection.
- Trying to sync a file that’s open in another app. OneDrive can’t upload a Word or Excel file while it’s open and locked. Save and close the file, then give OneDrive a minute to pick it up.
- Panicking if cloud files seem to disappear. If you accidentally deleted files while troubleshooting, check the OneDrive Recycle Bin at OneDrive.com — deleted files are kept for up to 30 days before permanent removal.
- Not restarting after Windows Update. Updates require a full reboot to take effect. If you installed updates without restarting, OneDrive — and much else on your PC — may not work correctly until you do.
Frequently Asked Questions
Why does OneDrive say “Processing changes” but never finish?
OneDrive is likely stuck on a locked file (open in another app) or a file with unsupported characters in its name, such as ?, *, or |. Click the cloud icon to open the activity center — the problem file is listed there with a specific error message telling you exactly what’s wrong.
How do I see which files failed to sync?
Click the OneDrive cloud icon in your taskbar. Any files with errors show a red “x” or yellow warning icon alongside a short explanation. This is the first place to look when diagnosing sync problems.
Does resetting OneDrive delete my files?
No. The reset command only clears local cache and connection settings — your files remain completely safe in the cloud at OneDrive.com. After the reset, OneDrive re-downloads metadata and resumes syncing exactly as before.
Can OneDrive slow down my PC or internet connection?
Yes — uploading many large files uses significant bandwidth and some CPU. To limit the impact, right-click the OneDrive icon, go to Settings → Sync and backup → Advanced settings, and set an upload speed limit that suits your connection.
What if only some folders won’t sync?
Those folders may be excluded from sync. Right-click the OneDrive icon, go to Settings → Sync and backup → Manage backup (sometimes labeled Choose folders), and confirm that all the folders you want are selected and checked.
OneDrive works on my phone but not my PC — why?
This points to a Windows-side issue rather than an account problem. Try Fix 5 (sign out and back in on your PC) and Fix 7 (update Windows). PC-specific OneDrive bugs are frequently patched through Windows Update.
How much free OneDrive storage do I get with Windows 11?
Every Microsoft account includes 5 GB of free OneDrive storage. If you have a Microsoft 365 Personal or Family subscription, you get 1 TB per person. Check your current usage at account.microsoft.com/storage.
Conclusion
OneDrive not syncing is almost always one of a handful of fixable problems: a stuck process, a full quota, a lost connection, or an outdated app. Work through the 7 fixes above — restart OneDrive, check your internet, verify storage, pause and resume, sign back in, reset the cache, and update Windows — and most users are back in sync within minutes.
Once syncing is working again, OneDrive runs quietly in the background and keeps your files protected automatically. If you run into other Windows 11 issues, browse our Windows 11 troubleshooting guides for free, step-by-step help.
