Shared Calendar Appointment Detail Not Displaying In Outlook 2016

The reason users just see Free/Busy is because the Outlook Group calendar was added from the Shared Calendars list.

Follow these steps in Outlook to add an Outlook Group calendar properly so you can see the appointment/meeting details:

1) In mailbox view, click to expand Groups.  Groups they are a member of will be shown.
2) Right click the group that has the calendar they want.  A context menu will appear.
3) Select “Add to Favorites…” in the context menu.  The group will now show in their Favorites list.
4) Switch to calendar view.
5) Under My Calendars, select the textbox next to the desired group.  Do not select the checkbox under Shared Calendars.  The calendar will now appear with all appointment and meeting details next to their personal calendar.

These instructions apply to Outlook 2016.
