Private appointments should be visible (but not readable) when sharing a calendar.
Private appointments are not displayed at all in shared calendars and displayed as free. On Outlook for Windows, the details of the private appointment are hidden for all but the owner.
This is unwanted behaviour.

This is not acceptable. My Mac users were previously able to see Private Events on a shared calendar, after updates at some point the functionality stopped. They are scheduling things so it creates a huge problem. It works when on Windows and through Outlook Web. This needs to be fixed ASAP. It's not a "product limitation" as I was told by support. It USED to work, and then an update broke it.

It is just anoying, working in a mixed business environment with Mac and Windows, if as a Outlook for Mac user making an appointment with several people and not seeing private appontments in shared calendars.
