Of course I have also 2 folders

1) SPAM from my internet provider

it could be fine to say to outlook "please use SPAM folder as
Junk-Email forlder" but this seems to be impossible (I hope to be
wrong ...)

You are correct. You cannot adjust which folder Outloook uses for Junk
E-mail.

An other problem is that in "Preferred folders" I have no evidence
of new msgs, while a sond is saying me that there are 1 or more new
nessages ... any idea about this ?

Not at the moment. I don't have access to my OL 2007 system right now. If
I get the chance, I'll look tonight.
