I have an Iphone 4s OS ver 5.1.1. I have been syncing my calendar with Itunes and Outlook on my personal computer without issue. I have started working for a company that uses Outlook and Exchange. I would like to get my work calendar on the Iphone, but not have my personal calendar, tasks, etc appear in the Outlook at work. So, I guess I want a one way push from exchange to the Iphone. Is that possible? Help!!!
