Thanks!
But I have a hard time to realize how to use that code to extract that 
data from a MailItem object. I guess I need some assistance. One 
alternative is to rewrite the code from msgstore.py to just extract the 
PR_TRANSPORT_MESSAGE_HEADERS provided a specific MailItem object. The 
other alternative is to use parts of msgstore.py directly. What I want is 
to get the headers and the body of all mails in a specific folder. How 
should I use msgstore.py to be able to do that?

Any assistance appreciated!

I can live with that :-)
