I'm currently evaluating zimbra as a communication platform.
One of the functionalities required is a shared calendar for a defined group of users to view, create and edit events.
The zimbra demo server is currently down, but as far as I remember correctly, there is an option to share calendars with 3 permission models (admin, read-only, can't remember the last one). Looking at these options, it looks like an view/create/edit-only option is not possible. Does anyone have experience with shared calender and can help me out?
