Perhaps my question got lost in my other long mail... 
So I want to open a new thread with the question: How can I index my mailbox on an Outlook/Exchange-Server? 

I know I can use the prog access method and write my own outlook/exchange spider program, but perhaps somebody has a ready-made solution?
So are there any solutions, tools or experiences (I did a search in the archive of the mail discussion list, but I found nothing)?
