Calendar and outlook 2016, private, busy, public

Hello there
using nc15, Outlook 2016 and Caldav Syncronizer, works fine so far
we share our calender in a group, and every other sees others calender as it shoud.
in the calendar via web i can define three status public, busy and private
but via outlook only 2 works: private and public. i cant get status busy into the web calender
(well the appointment goes up, but always in status public when setting busy in outlook)

any ideas?


push :wink:
no one with this problem?
