All of my users use Outlook 2003 and they all have an individual mailbox on an Exchange 2003 server. We have a email@example.com distribution list that goes to multiple people.
The sales department wants to be able to send out a newsletter, from their Outlook, but have it come from firstname.lastname@example.org. Of course I could create a real user account and real mailbox but that's not what I want to do.
I'd much rather find a simpler way for email@example.com to send mail as firstname.lastname@example.org.
