when I try to send an open word file by selecting send to recipient as
attachment it simply opens up outlook with the mentioned document in
attachment

when a perticular user tries to do this she gets an error message

bottom line is that this functionality only works for some people and
it will never work for others

where can I find info on how to solve this by changing settings in
office or in the registry or whatever

I have already googled and only found pointers to mapi errors telling
me absolutely nothing new
they all state that this is happening because outlook or outlook
express is not installed

but offcourse it is, otherwise I would not ask this question

the Office version is 2003 with SP1

thnx
