what is involved in having outlook email come to an iphone? We use Outlook 2007 on LAN with .ost file. The iPhone is a 4. Employee wants to check her company email with her iphone and respond to that email using her iphone. Two questions come to mind-first, how to receive the email on the phone, second, how to reply to the email where the reply is also in Outlook when she gets back to her computer?
