I had configured Folder Redirection with my local user account on Surface Pro 3 running Windows 10 Pro with v1709. After upgraded to the latest build of v1803, the AppData Folder is not longer getting redirected. I open the folder properties and the location tab is missing, so it is not way to manually map it. Then I try to apply that via GPO, but it gets “Redirection setting=0×1021.Error: The folder can’t be redirected. Unknown error” messsage. How can I resolve the problem?
It seems that the AppData with Folder Redirection feature has been removed or changed on Windows 10 v1803. Many users have faced “this folder is not redirectable” issue. Here are some useful tips to fix it.
If the AppData Roaming Folder doesn’t function the Redirection in your domain environment, go to install latest admx update and language files (april 2018). But the method only works on some PCs. For other Windows 10 machines don’t take any effects, try to set up the correct registry key.
* Press Win + R from your keyborad, type regedit.exe into Run dialog box, and click OK button to open the Registry Editor.
* Under the HKEY_CURRENT_USER folder, navigate to the sub-location:
and then select the User Shell Folders.
* Go to its right side pane, double click on the AppData, change its Value data to %USERPROFILE%\AppData\Roaming, and click OK button to save that.
However, adding the value as a Registry preference might be not function when the
%USERPROFILE% is the
%SYSTEMDRIVE%\Users\%USERNAME%. To get rid of that, you could export the correct settings from other PC and use the REG IMPORT command to import the data. Another way is to downgrade everyone back to v1709.
