You may also encounter this issue if you have the Windows update KB4592449 installed on your Windows 10 device. The update in question contains an application programming interface (API) change that causes Work Folders to fail to sync files from the server to the device.

If you’re faced with this issue, you can try either of the solutions presented below to resolve the issue. Let’s take a look at the description of the process involved concerning each of the listed solutions.

1] Uninstall buggy update for the time being

Since the Windows update KB4592449 has been identified as a culprit to the Work Folder sync error, you can simply uninstall the update from your device to resolve the issue. Alternatively, you can update to the next available build, as we do not recommend uninstalling updates, since Windows updates often include feature enhancements and security updates to protect Windows 10 computers from malware and virus attacks.
