Set my outlook calender appointment east cost time for 7am but when i went to the west coast it changed the appointmnet to 4am
correct because you're in the West coast time.
You have Time Zone support turned on. 4 AM on the west coast IS 7 AM where you were. You need to specify the time zone for the appointment if it is different from the one you're in when you create it.
