I have an Exchange Server 2003, server and have implemented a public calendar accessible from OWA. The calendar has defauly and anon rights set to reviewer and i have created a security distribution group called calendar editors that has edit rights (please refer to screenshot)
I have two users: user1 and user2. User1 is a member of the edit calendars group and user2 is not.
User1 can add items and user2 cannot - when I tested which is great.
BUT if I change the membership of user1 and remove membership to calender editors group, they can still add items to the calendar.
Does anyone know what is wrong???
