what is a clean reinstall with outlook? a normal uninstall via windows uninstall and then reinstall resulted in still the same problem, yes.
thx again.
--------edit
is there nobody who can help? would be much appreciated!

well since nobody wanted to help me

, i just went and bought office 2007, and everything runs just fine with this version. so whatever the cause may have been, it was definitely a problem with office 2003.
hope this helps somebody else. greets.

with office 2007 after one week of using it, i encountered a similar but slightly altered problem: word 2007 now crashes the user interface of windows media player. task bar is working just fine, other office programmes work just fine. so everythings fine but media player and word won't work together (haha). AND the problem seems to be a programme called "endnote". endnote + word + x64 OS kills things. greets. no solution yet, but the problem is minor
