Here's an updated link that sets the Calendar sharing option. This must be done at the organization-wide level by an administrator.

Options are

Only free/busy information (hide event details): Users can allow people outside your domain to know when they are busy or available, but event details are hidden. Private addresses are hidden from users' calendars.

Share all information, but outsiders cannot change calendar: Users can share their calendar information with people outside your domain. This includes guest list, location, and description. Private addresses are hidden from users' calendars.

Share all information, and outsiders can change calendars: Users can fully share their calendar information with people outside your domain. This includes guest list, location, and description. Private addresses are displayed.

Share all information, and allow managing of calendar: Users can fully share their calendar information with people outside your domain, and they can grant outsiders permission to manage their calendars. Private addresses are displayed.
