Look at the Application.Inspectors.NewInspector event. It will not let you
cancel the action.
You can also trap the MailItem.Open event (which is canceable), but that
means that you will need to set an an event handler on each selected
messages and track the selection by using the Explorer.SelectionChange
event.
