Scenario:- 2 companies merge who have there own registered domain names and owned by a large group with its own registered domain. The email address is the owning groups name but they may want to change it to one or both of the merged companies names when they roll out Exchange 2000. The question is setting up of external and internal namespace.
What is the best suggestion for initial setup (without Exchange, its 6 months away) and if local is used as internal can it be changed simply to reflect any corporate decisions that may be made in the future regarding email addresses. I know its a lot to take in but any advise is very much appreciated
