I upgraded from an older thinkpad laptop to a new one, XP to 7, and Outlook 2003 to 2007. When I migrated files to the new computer using the microsoft migration system I found that though I can access my contacts, the contact file are not recognized as an address book by the email system. Even within the contacts program the name search doesn't work, saying there are no contacts! The program says I must "certify" the contact files as an address book, but the "certification" menu within the file settings section has that check box grayed out.
I want to upgrade to 2010 later this year but don't want to buy it till I get this settled.
