I have just upgraded my users from Office 2000 to Office 2003.
When users were using 2000 they complained that some people could send
straight from Excel instead adding an attachment to an email and sending it
from there. I fixed this issue, in 2000, from looking on the Microsoft
website and making sure that a dll was in the correct area and it worked from
there.

But since upgrading from 2000 to 2003 that functionality has gone. I checked
if there was any changes from 2000 to 2003 on the website and it told me to
do the something as with 2000. I double checked the settings which I changed
in 2000 they have stayed but they still cant send from Excel.
