I am trying to setup a user to respond to emails going into a public folder named "billing". However when they respond outlook obviously reply's back to the email from "firstname.lastname@example.org", not "email@example.com". I need for reply's from the "billing" public folder to show the public folders email address instead of the users email address. How can I achieve this within the users outlook box? Also there will be other users as well replying which would need to do the same thing. We are using outlook 2010, and exchange 2007.
