Well.. I have a suggestion myself, and it DOESN'T have to do with an additional script.

Just use the script mentions on the last page, and (in outlook 2007) (i dont have 2003 anymore.. sorry for that)

Go to Extra>Makro's> Security. There go to the tab "Makro Security" Also i have a Dutch office 2007, so don't mind my rubish english. Myself I have the setting on "No Secrurity for all makro's (NOT RECOMMENDED). Most people would say that Warnings for all makro's are recommended. But with all my makro's, that's just not worth it.

Next select OK, and reboot outlook.

This SHOULD enable the makro.. Ofcourse you CAN add the script in the post above this one, to make sure it all works.

Hope this helps!
