Hey.

I've been waiting to see when somebody finally got around to testing
Outlook express. 

It's also possible to exploit this through Outlook full version from
office 2003. 

I have also discovered other problems (not difficult to fine) which
allows the execution of any program which has registered as a 
document handler, with the URL been passed to it. 

This gets interesting when the local application has problems such
as a command line buffer overflow.

I'm guessing this is similar to what has been documented here.
