Until now it was almost impossible to get a good overview of your team's or office Contacts integrated with Outlook. TeamContacts is an easy to install Outlook add-on, which solves that problem effectively and flexibly by sharing your Contacts database.
You can filter the Contacts that you want to share (and take with you on your PDA) by using categories. All of these features are available on a simple network, LAN or even a peer to peer network. No server software is required but it works great with Public Folders.
