I'm installing Exchange 2007 and I'd like to know what the best way to install, prapair and configure and ensure that I do not interupt my current email domain, which is hosted on a pop3 server (outside). While installing the Exchange I figure I would use a domain name that I registered with godaddy for our Citrix server. I point the A records to Citrix and I figure I'll point MXRecord to my Exchange. Not sure what the best way to achieve this with out interupting current email domain until Exchange is ready.
What is the best solution for this situation?
I appreciate all your help.
