Here is my situation:
I have an external ISP providing email to our company through our domain name, for example: mail.businessname.com. I've setup an Exchange Server 2003 with an internal domain of 'businessname.corp' (I would have used .local knowing what I know now but that is another story). I can get email on and off the exchange server from several clients with no problem.
So now my plan goes like this:
1. Setup a clients so they can check the current pop3 account through exchange server. This also involves user names, logons and passwords to the external POP3 account are different. I'm not sure how to handle that. At the same time I'd also like to set it up so that the data is stored on the exchange server instead of the client workstation.
2. After all clients have been setup and tested, we will have the ISP change the 'mail.businessname.com' name resolution to point to the IP address of our exchange server. It is hoped that while the name resolutions are changing over that the ISP will relay the emails to our exchange server using the IP address. After 72 hours or whenever the names finish changing over we would no longer have need for the ISP email server.
3. Ideally we would like this to be accomplished in such a way that we only have to configure each client one time.
What steps do I need to take to reach my goals here?
Thanks a bunch in advance!
