OneDrive Not Syncing? 8 Fixes for Windows 10 & 11
Updated: Sep 27
OneDrive is supposed to work quietly in the background, so it's easy to miss when it stops. Then one day a file you saved at work isn't on your laptop at home, or the cloud icon in your taskbar has a red X. I see OneDrive sync problems all the time, on personal PCs and on business laptops. Most are fixed in a few minutes. This guide starts with the quick checks and works up to the fixes that solve the stubborn cases.
First, Check the OneDrive Icon
Look for the OneDrive cloud in the notification area at the bottom right of your screen (click the ^ arrow if you don't see it). Its appearance tells you where to start:
Gray cloud: OneDrive isn't signed in. Click it and sign in with your Microsoft or work account.
Red circle with a white X: a file or folder can't sync. Click the icon to see which one and why.
Pause symbol: syncing is paused. See Fix 2.
Cloud with a line through it: you're signed out or offline.
No cloud at all: OneDrive isn't running. Open it from the Start menu. If it won't start or closes right away, skip to Fix 6.
Fix 1: Restart OneDrive
Like any app, OneDrive can get stuck. A restart clears it more often than you'd expect.
Click the OneDrive cloud icon, then the gear icon.
Choose Quit OneDrive, then confirm.
Open the Start menu, type OneDrive, and open the app again.
Give it a few minutes to catch up. If it still isn't syncing, restart the computer as well.
Fix 2: Make Sure Syncing Isn't Paused
OneDrive pauses itself when your laptop is in Battery Saver mode or on a metered (limited data) connection, and it's easy to pause by accident. Click the cloud icon, then the gear icon, and choose Resume syncing.
Fix 3: Check Your Storage
OneDrive stops syncing when there's no room, either in the cloud or on your computer.
Cloud storage: a free Microsoft account includes 5 GB, and Microsoft 365 plans include much more. Click the cloud icon, then the gear icon, and choose Settings, then Account, to see how much you've used.
Computer storage: if your drive is nearly full, OneDrive can't download files. Go to Settings, System, Storage to check, and turn on Files On-Demand (next tip) to free up space.
Tip: Files On-Demand lets you see all your OneDrive files without downloading them. In OneDrive settings, go to Sync and back up, then Advanced settings, and turn on Files On-Demand. Files download only when you open them.
Fix 4: Look for Problem Files
One bad file can make it look like nothing is syncing. Click the cloud icon to see any files with errors, then check for these common causes:
Characters OneDrive doesn't allow: " * : < > ? / \ | in a file or folder name. Rename the file.
Names that are too long: the full path, including every folder name, must be under 400 characters. Shorten folder names or move the file up a level.
Files that are open: a document open in Word or Excel may wait to sync until you close it.
Very large files: the limit is 250 GB per file.
Fix 5: Update OneDrive and Windows
An outdated OneDrive app can stop syncing after a Windows or Microsoft 365 update. Run Windows Update (Settings, Windows Update, Check for updates) and restart. OneDrive normally updates itself, but you can download the latest version from Microsoft's OneDrive download page and install it over the top.
Fix 6: Reset OneDrive
Resetting OneDrive clears its settings and rebuilds its sync connection. It does not delete your files, but it will re-sync everything, which can take a while if you have a lot of data.
Press Windows key + R to open the Run box.
Copy and paste the line below, then press Enter:
%localappdata%\Microsoft\OneDrive\onedrive.exe /resetIf Windows says it can't find the file, try one of these instead:
C:\Program Files\Microsoft OneDrive\onedrive.exe /resetC:\Program Files (x86)\Microsoft OneDrive\onedrive.exe /resetThe cloud icon will disappear and come back after a minute or two. If it doesn't, open OneDrive from the Start menu. You may need to choose your sync folders again afterwards.
Fix 7: Unlink and Relink Your Account
If resetting doesn't help, disconnecting the account and signing in again gives OneDrive a completely fresh start.
Click the cloud icon, then the gear icon, and choose Settings.
Go to Account and click Unlink this PC.
Sign in again when the setup screen appears and choose the same OneDrive folder location.
Your files stay on your computer and in the cloud. OneDrive just matches them up again.
Fix 8: OneDrive Is Blocked by Group Policy
This is the one I see on business computers and on PCs that used to belong to a company. The symptoms are distinctive:
You are never prompted to sign in to OneDrive.
Files don't sync, and no error message appears.
The OneDrive folder doesn't open when you select it from the Start menu.
This happens when a Group Policy setting stops OneDrive from starting. Because the policy keeps blocking it, uninstalling and reinstalling OneDrive or Microsoft 365 won't fix it, and neither will Microsoft's support and recovery tools.
Before you change anything: if this is a work computer managed by your company's IT department, the block may be on purpose. Check with them first. They may also have the policy set to re-apply, which would undo this fix.
To remove the block on a computer you manage yourself:
Open the Start menu, type regedit, right-click Registry Editor, and choose Run as administrator.
Go to this location:
HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows\OneDrive
Double-click DisableFileSyncNGSC, change the value from 1 to 0, and click OK.
Restart the computer, then open OneDrive and sign in. Everything should begin syncing.
Still Stuck?
If OneDrive still won't sync after these steps, or you'd rather not edit the registry yourself, IT-Tech can connect to your computer remotely and sort it out, usually in a single session.
Book a remote support session and we'll get you sorted out.
