Proxy Access - Send appointment


With GW 2014 R2, I can't send new appointments by "right click - new appointment" anymore when I'm in a user's calender via proxy access. If the user gives me write access to his calender, it's working. In GW 2014, it was working although I don't have write access, I could send him a new appointment anyway.

Is this a bug or a wrong setting? Or is this behavior correct?

Thanks and regards,
