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The reason for OneDrive sync issues can be temporary glitches in the system, an outdated app version on your system, or running out of available storage.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As mentioned above, the outdated OneDrive app is one of the reasons for OneDrive not syncing.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.

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.
