I have generated my first Exchange 2007 Standard server. This is an all-on-one-server "simple" installation, so no Edge component (right?). During the install I chose a private domain name (ClientDomain.local) with the intent of adding the published external name (ClientDomain.com) afterwards and making it the default email domain.
After an apparently successful install, I added a New Accepted Domain in the Organization Configuration > Hub Transport, but it doesn't show up as a drop-down option when I create a new Recipient Configuration > Mailbox (I miss AD integration!).
What do I need to do to 1) see the .com domain new user drop down; and 2) how to make the .com the default email domain.
