1) Use Microsoft Windows SharePoint
2) Office One Note 2007
In SharePoint, you can create a contact list for your entire team and then each member of the team can link that address book to Outlook by clicking the Link to Outlook at the top of the contact list in SharePoint. SharePoint 3 is a feature of Windows Server 2008. As such, someone with access to your Windows Server 2008 server will have to activate this feature and set up your users with appropriate access.
Office OneNote 2007 is another option. OneNote will allow you to create a shared notebook that you can populate with address information. Your team members will be able to access the shared note book and view the address data.
