Could you explain how I can set up the account as an exchange account?
I don't know the first thing about iPhones, but I would reckon that all you have to do is install the Outlook for iOS app.
And when I do will that change anything else about my mail, contact, or calendar?
I can't imagine what that might be. What are you afraid of?
I was able to access my email and calendar thru the existing apps on my iphone and ipad. The mail is still accessible but as we've noted already the calendar is not syncing so I can't get to any of my upcoming appointments. My concern in changing things is losing any information I may already have such as contacts or stored email files. As it is I'm not sure if I have lost information already from my calendar or if it's just a matter of getting access to it some time once sync issue is resolved.
