If Add2Exchange was working and now it's not, post here.
Here's my scenario. User A manages the schedules of users B, C and D. I've set up private to private sync so that the calendars of users B, C and D appear in User A's calendar on her iPad and iPhone. When B, C or D accept a meeting invitation, the meeting does appear in their respective Outlook calendar, What's not happening is User A's view of B, C and D's calendars doesn't reflect the accepted invite/appt. Any thoughts?
