Hi Robert,
many thanks! That´s exactly what I´m looking for I think. I´m only struggling with one last thing... the Export-CSV-Thing... My understanding would be someting like
$myVariable | Export-CSV blablabla..
But how would i define the $myVariable in your script?
I´m sorry for those really stupid rookie-questions ... have to talk to my boss that I need time and lessons to learn this stuff 
Thanks,
Markus
