We have 22 people that are syncing email, calendar, and contacts between their iPhones/iPads and our Exchange 2003 SP2 server. We have been successful in doing this over the last 2 years, with no real problems other than wrong information entered on the mobile device.
Several days ago, my CEO (isn't it always) reported that his calendar was not syncing correctly on his iPhone or iPad. CEO is still syncing email and contacts successfully. The symptom was that there were calendar items missing on his mobile devices. No other users have experienced this problem.
I tried deleting the account on his iPhone, restarting iPhone, then adding Exchange account. Account is added successfully, but calendar only does a partial sync. Some appointments appear but many are missing when I compare it to what I see in OWA.
The fact that this is happening to only one person and only with the calendar makes me think there is something corrupt with the calendar, but I'm not sure what steps to take from here.
Any guidance from you would be greatly appreciated.
