This is the first Exchange migration I have done with multiple Exchange servers (and each server has multiple roles). Can someone help me fill in the blanks? I would like this to be a streamlined as possible, but I am not sure of the best configuration of the URL's to accommodate my environment. Can this be setup so that all users go to a single URL internally and externally regardless of the site their mailbox is located (have OWA, OAB, ActiveSync, and Outlook Anywhere all use the same URL both internally and externally)? I know Exchange does its own proxying, I'm just not sure if it's complex enough to sense what we are doing here.
The Exchange environment is virtually untouched at this point. The only thing that has been done is that I have installed/patched the OS on the machines that will host the new Exchange environment. Any advice direction will be greatly appreciated.
Here are the environment details:
