configure outlook web access?

I am just getting some exchange knowledge. I need to know how to change the settings for people's addressbook. What happens is when they create a new email and click on the address book, they would like a full list of the contacts. Not have to run a search. Silly yes, but I can't find it anywhere!

What version of Outlook are your users on?

it's all 2003 (SBS 2003) but my understanding is that it is OWA that is causing the problem it works fine in outlook connected to the exchange box, it is under the OWA that they are whining.
