I have many iPhone 4s and 3s in use. They all use activesync. We have a 2 year old SBS 2008 server running Exchange. Users are frustrated that the many and varied public folder based calendar, contact folders, etc. are showing up on their iPhones. Its confusing since they are only identifed genericaly on the iPhone. We really don't want then synching the public folders anyway. How do we turn this off so they only get their personal folders syncing?
