Use Outlook 2007 instead of OWA

Hello!!!
Hello!!!
At work we have an exchange server 2003, which gives us access to
emails, calendar, taks, etc… through OWA. (server.domain.com/
exchange)
I was able to synchronize everything on my Blackberry, PDA and
Entourage (Mac OS X).
all of them had an option for OWA. but i’m unable to do the same
thing with Outlook 2007
It wont connect. I’m putting the same web address for the OWA but
it’s not connecting.

any idea ? pleaseeeeeee !!!!
