Avast 2014 premier and Outlook 2007

I updated my avast to 2014 premier. Now my wife’s desktop outlook 2007 won’t send/receive emails. My computer and my wife’s laptop work fine. When I turned off avast, it could send and receive emails. I don’t know what setting in avast is blocking her’s. I’ve looked around, but no solution. All computers are running win 7 64bit. Mine and my wife’s desktop is pro and the laptop is home premium. All running office 2007 pro. Any ideas?
