I'm running windows 7 Ultimate 64 bit and using Windows Live Mail.  Recently, the categories that I have set up in contacts are not saved so that when I try to email a category, there are no contacts in them .  I have gone back and re-entered the contacts and clicked save but It still doesn't save them when I go to use them.  
Frustrated

I exported the Oultook PST file from a Windows 7 Ultimate/Outlook 2010 PC and then imported it to Outlook for Mac 2011 ( Mac OS X Lion).  Some of the attachments have been transferred but the majority have been lost.

 

Is there some setting I should have made prior to exporting the file or prior to the import?
