one of my client has requested a form that sends the email feedback to a Distribution List in his Outlook Contacts. So…is there a way to code a form to pull the emial addresses from an Outlook Contact distribution list?

This looks like an attempt to steal email addresses from an address book and spam the heck out of them. Is that what you are trying to do?

You can save the contacts as a text file and input them all to a database which is stored on the web server.Then when the form sends an email it can send it to all the addresses.

If your outlook uses exchange server on active directory. I believe you can then query the server using ldap to get what you want.
