Trying To Use 2008 Express To Export Outlook 2000 & Outlook 2003 Address Contacts Into Excel Or CSV File

I work for a somewhat large company.There are about 160 Windows XP Pro users. We are still using Microsoft Office 2000 for the most part.We have upgraded some users to Office 2003. We are not using Microsoft Exchange.I have to export every users' Outlook 2000 or Outlook 2003 Contacts into an Excel or CSV file every 6 months as a way of backing the Outlook Address Contacts.Currently I am doing this by physically going to every pc and manually exporting the contacts.This is a large pain.I am trying to find out if I can use or create a Visual Basic 2008 Express program or script that will export the contacts from Outlook and save it as an Excel or CSV file.The name of the file should be the same as the computers net name.It should be saved in the same location, on the network, each time.I am new to programming and new to VB 2008 Express.I do not know or have any code to start with.
