We will be moving exchange accounts from one machine to another (exchA and exchB). After this move we will be removing exchA from the AD domain and renaming exchB to exchA. How will this effect the outlook clients assuming the clients were originally pointed at exchA for mail.
Another way to look at this question is do the outlook clients use DNS or SIDs to find and talk to the exchange server.
The environment is AD2000 with exchA running Exchange2000 and exchB running Exchange2003. The clients are a mix from Outlook XP to Outlook 2007.
