AppointmentItem.GetInspector Property (Outlook)
Returns an Inspector object that represents an inspector initialized to contain the specified item. Read-only.
This property is useful for returning an Inspector object in which to display the item, as opposed to using the Application.ActiveInspector method and setting the Inspector.CurrentItem property. If an Inspector object already exists for the item, the GetInspector property will return that Inspector object instead of creating a new one.
