Appointments on one users calender are marked as busy. If you try to schedule a meeting for 10 on Friday (which is busy) it shows up on my end as open. But the time that is marked busy on thursday I can see on my end as busy. Only certain days do not show the times that are busy. This friday, next monday, next friday, etc. all display the busy times as free. But all the other days function correctly. Any clue?
