OneDrive, launched by Microsoft in 2007, allows users to store personal files, folders, and Windows settings to the cloud. Most of the time, this Microsoft app works as expected and syncs all your data and files without any issues. However, sometimes you may experience, OneDrive is not syncing some specific files or folders.
The reason for OneDrive sync issues can be temporary glitches in the system, an outdated app version on your system, or running out of available storage. If the files you want to sync have a duplicate name or unsupported characters in the name, you may not be able to sync it. Many other reasons can restrict the syncing process in OneDrive. Whatever the reason for the OneDrive sync issue is, we have got you covered with solutions to fix it.
Solutions To Fix OneDrive Not Syncing Issue
If you frequently sync files to OneDrive cloud to access it anywhere and everywhere, the sync issues can be a headache for you. With the below mentioned fixes, you can quickly fix OneDrive sync problems and start syncing files/folders again.
1. Check File Name, File Path, and File Size
There are some restrictions on file name, file path, and size of the file while syncing it to OneDrive. You can check if your file does not have any unsupported name and path.
The maximum file size you can sync is 20GB, so make sure any of the files you are trying to sync is not crossing this limit. If you see error messages like ‘file size is too big to upload’ or ‘reduce the file size,’ you can zip the file and then try syncing/uploading it.
The next thing to check is, the file name shouldn’t have any special characters like –
<, >, :, “, |, ?, *, /, .
Also, check if the folder you want to sync contains the file type like thumbnails or previews, which is not supported by OneDrive. You can change the file name, remove the unsupported file type, and then sync files and folders again.

The file path which you are trying to sync should be less than 400 characters. You can change the file name or some subfolders and make it less than 400 characters so that it can sync to OneDrive without any issues. If you have performed all the checks mentioned above and still OneDrive is not syncing, then the issue may be with something else and not the file name.
2. Update OneDrive
As mentioned above, the outdated OneDrive app is one of the reasons for OneDrive not syncing. The most recent version of the OneDrive app can be downloaded from Microsoft’s official site. And then run the downloaded exe file to install it.
Post the install, search for OneDrive in the search menu and open it from the search result. You may need to log in again to your Microsoft account and set it up if it is not synced automatically.
Once the account is ready, check if you can sync OneDrive again. If not, you can check out other solutions mentioned below.
3. Update Windows
You can download and install the recent Windows update to fix OneDrive sync issues in Windows 10. The bugs and other issues are fixed in each Windows update. So, if OneDrive won’t sync because of bugs, the Windows update will fix it.
You can press the Windows button and click on the settings icon there to open the Settings app. In the Settings app, go to Update & Security and then click on Windows Update from the left panel. Next, click on Check for Updates.
Download and install the update if available and then check if this fixes syncing issues in OneDrive.

To restart your computer, you can press the Windows button and then click on the Power icon. Click on Restart to restart your system.
Post restart, check if the OneDrive is syncing your files and folders normally. If not, then you may need to unlink OneDrive or perform some other fixes.

9. Perform an SFC Scan
The sync may not work as expected if Windows system files are damaged. The SFC scan can detect and fix corrupt and damaged system files. To use the utility, execute the sfc /scannow command.
Open the command prompt as administrator, as explained in the above solution. When the command prompt opens, type in sfc /scannow and hit Enter to execute the command.
If there are any corrupt files, Windows will replace it with a new one. However, if there is no issue with system files, you can head towards the next solution to fix OneDrive not syncing issues.
10. Move Files from Sync Folder to Other Folder
Sometimes, moving two or three files from the sync folder to some other folder, which is not synced to OneDrive, helps in fixing sync issues. Before moving the files, you need to pause the sync.
To pause the sync, right-click on the OneDrive icon and then click on Help & Settings. In the opened menu, click on Pause syncing and then click on 2 hours.
After you pause sync, move some files to another folder, which is not related or synced to OneDrive.
You can then resume syncing by clicking on Help & Settings ➜ Resume syncing.
You can now check if the OneDrive not syncing issue is fixed after this. And if the sync is working normally, you can move the file back to the sync folder.
11. Check Available Storage
OneDrive won’t sync files if there is no storage available on the local machine or cloud. You can check the available cloud storage by right-clicking on the OneDrive icon and then navigating to Help & Settings ➜ Settings.
When the Microsoft OneDrive window opens, go to the Account tab and check how much of your cloud storage is used.
If you don’t have enough cloud storage, you can delete some large files from OneDrive or purchase extra storage. However, if you have enough storage available on OneDrive, you can check local storage by going to File Explorer and then to This PC.
You can make space in the local storage by deleting unwanted files and software from the system. If you have enough space in both the mentioned places and still the OneDrive is not syncing files, you need to try some other fixes.
12. Delete OneDrive Cached Credentials
If you recently changed your Microsoft account password, the chances are OneDrive is not aware of such change, and therefore sync is not happening. In such cases, you need to remove old password and information from OneDrive, so that it can process new credentials. Follow the steps below to delete OneDrive cached credentials.
Step 1: Type credential in the search box and open Credential Manager from the search result.
Step 2: Click on Windows Credentials

Step 1: Click on the OneDrive icon and then navigate to Help & Settings ➜ Settings.
Step 2: Go to the Office tab and uncheck the checkbox next to ‘Use Office applications to sync Office files that I open.’
Step 3: Click on OK to save the changes you made.
Post this change, check if you can sync Office files or not. If still OneDrive is not syncing, you may need some other fixes.
14. Compress Files and Folders
You can compress the large files and folders so that there is no issue syncing them. The max limit of file size is 20GB, as mentioned above. So, if your particular file and folder is above 20 GB, then compressing them is the ideal thing to do. As one must make sure it does not cross the max limit.
To compress the folder, right-click on it and select ‘Add to archive’ from the context menu.
And then, select the format you want to archive your files and click on OK to save the changes.
Once you compress the folder, try syncing it and then check if you can do it without any issues.

Step 1: Click on the OneDrive icon seen on the taskbar and then navigate to Help & Settings ➜ Settings.
Step 2: When the window opens, go to the Network tab, and select Don’t limit under Upload rate and Download rate.

To disable the antivirus, visit the manufacturer’s website and check how to do it as every antivirus has a different way of disabling it.
To uninstall the antivirus, open Settings and go to Apps. Click on the antivirus installed on your system and then click on the Uninstall button.
Now, check if the OneDrive started syncing files and folders again. If it does, you can talk to the customer care executive about the issue. You can also use other malware remover software or antivirus, which does not cause such issues with the system.
