I am currently using Microsoft Exchange 2003 on Windows Server 2003 with various iPhone 3G, 3GS, and 4s. The iPhones have all been upgraded to the latest firmware. Users are using Outlook 2007.
An example I am finding is that normal calendar events added from either Outlook or iPhone sync fine but if I am the "meeting organizer" sending a "meeting request" the event will show in my Outlook but not on my iPhone.
Is there any good list of Exchange/iPhone ActiveSync limitations? Any workaround for the issue above?
