import microsoft exchange email contacts to website

[SniperB]

So I'm writing a web page to import contacts from a bunch of different sources such as Gmail, Yahoo mail etc. I've mostly found solutions on my own to importing these, however there is one source I'm having trouble with.I want to import contacts from Outlook in the same kind of way that LinkedIn does, so far the best information I've found on this subject is here: http://weblogs.asp.net/whaggard/arc...outlook-contacts-from-my-web-application.aspxAs far as I can tell it seems that LinkedIn gets your email address, exchange account username, and password, and somehow from this it finds your exchange server address and port. I'm wondering if anybody knows how to get the exchange server info from your email, username and password so I can then use the above link to import contacts.
