My company has requested that I change our email domain name to something easier to type. We have a single exchange server running 2003 and hosting our email domain firstname.lastname@example.org. The company would like to change from email@example.com to firstname.lastname@example.org. Is there an easy way to have users retain their emails and data with going to a new domain? I know I have to create new pointers to the new name from our outside DNS but unsure how I would internally go about this change in AD/exchange. Thank you in advance and I humbly await for any help that might be out there.
