Emailing anything from Office 2007

Hi I am running Office student Edition 2007 on windows XP SP2, outlook
express (6).
When I create a file in any of the office programmes (Power point , word
etc) I can not Email the file directly from the programme I have to save it
first, open outlook create my message and then attach the saved file.
When I create the file in say, Word, go to the office button, and go to
send, the Email option is greyed out.
It's just a pain to not be able to send straight from Office 2007, any
thoughts??
