All day activities in MSA do not replicate correctly in outlook. If I create an all day activity in outlook, the activity is syncronized so I will find the appointment in outlook, but it will not be marked as all day appointment, and the time will not be from 12 am to 12 am of that day. Instead, I found that the system keeps the duration of the activity to 12 hours, but not starting and finishing in the same day.
However, when those all day appointments are created in outlook, they are refleted as all day activities in MSA so it works fine.
Thanks for your help,
