For the longest time, we operated a relatively simple Windows AD single-domain environment. We have recently partnered with an external organization to acquire a large contract, splitting the workload between teams. As a result, I'm receiving a few specialized requests.
Messaging Environment: Exchange Server 2007 (DMZ-based Edge Server (1 role on 1 box), LAN-based Hub, Client Access, Mailbox and UM server (4 roles on 1 box))
Task: find a way to send and receive email that is from the new domain name established between my organization and the partner, call it 'newdomain.com'. A handful of internal employees within my company need to send and receive emails from email@example.com. To make things interesting, another handful of folks at (potentially) several external organizations need to receive and send mail using firstname.lastname@example.org as well. Of course, both internal and external folks will work mainly from their longstanding, already-existing email accounts (email@example.com). I need to find a way to add this new functionality for the use of both teams, internal and external. I've been asked to achieve this using our resources for both teams...is that possible?
Thanks in advance-
