Problem with SketchUp saving preferences (folder redirection AppData)

We use folder redirection of the appdata folder on workstations to a share on a network server. In the appdata folder the preferences files (json) are stored.

Since we replace our Windows Server 2008 R2 server with an Windows Server 2016, Sketchup is unable to write the preferences files to the network location. I have everything checked, but permissions on the share are not the problem afaik.

I check with Monitor Explorer the actions by the Sketchup.exe process and I see some overflow errors and access denied.

Is there somebody that knows this problem and how to solve this?
