I updated my iphone 1.0 to the 2.0 firmware and have an issue with the Calendar items that sync'd from my Exchange server to the iphone. I can not edit any calendar items (all-day events, appointments, etc.) on my iPhone that were not created on the iPhone. So, all of the calendar items that moved to my iPhone can not be edited. The only thing I can do is change the reminder. If I create the calendar item on the iPhone, I can eidt it and it does sync properly. Also, it wasn't until I marked all calendar items as unread in Outlook did all of the items come over to the iPhone. Prior to that only recurring items came to the iPhone. This is very odd behavior and unless I can edit all Calendar items on the iPhone and have the changes sync, this new sync feature is useless to me. Also, the calendar items all came over as meeting requests each asking me to accept, maybe or decline. Accepting did not change the behavior of the editing. I have a very long list of meeting requests, one for each appointment. I think this implementation is buggy, or I have to change something that I have not identified, yet. Contacts are fine, so is email. Anyone have the same problems with Calendar items and Exchange Sync? Any solutions?
