Folder Redirection Fails. Event ID 502 - Access is denied

Issue

Applying folder redirection to Documents and other folders fails when Group Policy is trying to automatically create required folders. Following error is logged in Application Logs on client PCs:

Event ID: 502
Level: Error
Description: Failed to apply policy and redirect folder "Documents" to "\\Server-Name\Redirected\user.name\Documents". Redirection options=0x1021.
The following error occurred: "Can not create folder "\\Server-Name\Redirected\user.name\Documents"".
Error details: "Access is denied.".

As the error explains, this is permission issue. If user's folder on the server is created manually by an administrator everything works fine.
