I'm trying to help my wife figure out why she is getting numerous contacts with her work Microsoft Exchange. We also have MobileMe and she'd rather use that but I don't know much about the Microsoft Exchange. I do see when her iPHone is connected to iTunes it does say something about her phone is being synced over the air by Microsoft Exchange and the this may result in duplicated data showing on your device. Does anyone know how to remedy this? I think she'd be fine with just syncing with MobileMe and I've turned off syncing the contacts on her phone in the Exchange mail settings.
