I've created a contact list in Sharepoint Foundations 2010 that works wonderfully with Outlook 2010. We have data in the "Categories" column that shows in Outlook 2010 (on windows 7 pro) properly. However, when we connect the same contact list to Outlook 2003 (running on XP Pro sp3) the categories field is empty.
Is there a difference between the categories field in outlook 2003 and outlook 2010?
