I found that the outlook connector does not synchronize private appointments of a shared calendar.
User1 has a calendar A
User2 has a calendar B and shared calendar SA from User1
User1 create a private appointment in its calendar A with outlook connector
User2 not view the private appointment in calendar SA with outlook connector but its appear from web client.
User2 should be able to see that the time is occupied without seeing the contents since the appointment is private.
User2 does not see that the period is busy.
That's a bug from connector?
