Putting this in the iPad section, but..... I have an iMac, iPad and iPhone. Trying to get them all to sync with each other and the Outlook Exchange server that I HAVE to use for work is perplexing. Adding an appointment on the iPad does not appear on my iMac or iPhone. Sometimes by re-entering my password on the iPad an appointment will sync with the iMac, but not with the iPhone. And iPhone appointments don't sync with the iPad or the iMac. Is there some kind of consistent issue with Exchange servers and iCalendar?
