Trouble with OneDrive for Business and UE-V

Occasional Contributor


I have some Trouble with OneDrive for Business and UE-V on Windows 10 1809


  • Windows 10 1809 Enterprise x64 (Last Cumulativ Update)
  • Office 365 ProPlus Monthly Channel
  • Folder Redirection to the local OneDrive for Business Folder
  • active OneDrive Files onDemand
  • active UE-V withe default Setting Templates
  • Sync Provider configured as "external"
  • UE-V SettingsPackagePath is the local OneDrive for Business Folder


The Problem

  1. A Random Online-only File (cloud symbol)
  2. Client has internet connection
  3. When I try to open the file I get the following message
    • "Make sure you're connected to the Internet, then try again. We can download the file the next time you're online."



First insight

  • As soon as we disable UE-V on the client, the problem no longer occurs.
  • Simply delet the UE-V profile completely and restart the Client doesn't solve the problem.


Does anyone know this kind of failure?

Microsoft reports the bug in KB4512534 (August 17, 2019 for 1809). A fix is included in the same update. However, this only becomes effective if you set a corresponding RegKey on the client in Windows.


Link to the KB4512534:

  • " Addresses an issue that causes an error if you open Microsoft OneDrive files on demand when User Experience Virtualization (UE-V) is enabled. To apply this solution, set the following DWORD to 1: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\UEV\Agent\Configuration\ApplyExplorerCompatFix "


First tests confirm the effectiveness of the Fix.
