Emailing invoices using Windows7 and Outlook 2013 or 2010

Has anyone been able to email invoices from BV using Windows 7 64bit and Outlook 2010 or Outlook 2013.  Apparently something to do with mapi system changed by Windows 7.  I have been trying to find a solution as most of our invoices are emailed to customers.  It is a pain having to export to Adobe and then email from Acrobat.  It used to work with older software!
