How can I change the default permissions for everyone?

By default the calendars for staff or functional-mailboxes are set to enable other staff or functional-mailboxes to see the free/busy times of the calendars, meaning that the blocked times are visible but no other information like title, participants, content, etc… . Students are never able to see this by default.
This enables our staff to see for specific times if an appointment is possible with another person and is one of the key features of the Microsoft Exchange mail system.

    3. In the opening window click on the tab „Permissions“ and mark the entry „Default“:

    4. Change the permissions as desired.
    E.g. to show no details for your calendar, choose „None“ and then click on the „OK“ button:

  • MacOS

    1. Open Outlook on your MacOS device.

    2. Change to the calendar-view, rightclick on the desired calendar und click on “Sharing Permissions…”:
