A ipad has a exchange 2003 account setup and a iphone has the same settings for exchange account. It is supposed to be push but i have noticed that the Ipad and Iphone both show the number of new email when starting the email client on both devices. So it retrieves the email when starting the application. At my knowledge the email should be synchronised in the background, but it isn't is this to fix? It is IOS 6.1 in both devices..
