I have upgraded to Outlook 2010 and at the same time bought a new PC running windows 7 (64bit).
I had previoulsy upgraded to Outlook 2010 a few days before getting the new PC and the address book was working then.
I copied all the old .pst files to my nerw PC in the folder that Outlook was looking in when I went to file>open. After opening the largest and newest pst file all my old inbox and sent were there, but I can't find any contacts.
I have tried creating a new profile (though not really sure what I,m doing) but still no joy.
