Outlook address book

Hi,

I have a weird question. My company currently uses Microsoft Outlook XP for internal email. This is where all our addresses are stored. We are going to get rid of this internal email and go to and external, web-based service.
My question is this, how do I copy my internal address book so everyone has access to it? My current internal service is located on our server. I would like to export this list so it would be easy for all to have access to it, and to make any type of maintenance easy as well.
Does this make any sense?

Thanks again,

Ken
