When I send a meeting request in MAC Outlook, my wife who shares a calendar does not recieve the invitation but in order to accept it, but it does get placed on our calendar.

 When i send a meeting or appointment request in MAC Outlook, my wife who shares a calendar does not receive the invitation in her inbox in order to accept it, but it does get placed on our calendar.  When she sends me a meeting or appointment request, I receive an email that allows me to accept the invitation.  I want her to have the same ability to receive the invite and be able to click accept or deny before the meeting gets placed automatically on our calendars...
