Outlook 2012 how to stop unaccepted meeting requests from showing in calendar?

I have a stand alone Outlook 2012 instance.

When I get a meeting request but never even read the email/request.  The event shows up in my calendar.  as "not yet accepted" 

I want to NOT show anything in my calendar unless I accept the meeting... I turned off the tracking but they are still there..

The issue is that my calendar is already synced with work.. so the meeting is already in my calendar .. since the email is also synced I get a dupe of every work meeting in my cal.. even  though I do not accept the copy of the meeting invite or even open the email so I never want to see it in my calendar unless I accept it.. how do I do that?
