I have a DI and also a macbook with mac email. I migrated from mobileme to iCloud, although I don't yet have Lion, just SL. I can't set up my DI to receive mac email, however I was recently receiving it on my droid until the change. I've tried all the apple support forums and tips, yet nothing works. I keep getting a message indicating it can't find the exchange server. I've put in smtp and imap. It asks for an exchange domain - no clue. I am not prompted for any port numbers. Really Frustrated.
