They obviously have a newer version of Outlook than you, and in their version they have different headings for information. What you need to do is have them export their contacts as a csv file- comma separated values (windows). Then you need to export your existing contacts in the same format. Open both via excel and make sure all the headings on the top row match. If there are any that you do not have, remove them from his/hers. If there are some that are named differently, ie Full Name verse Name, make sure to change theirs to match yours. After you have done that resave theirs in excel as a csv file and import it into your contact list. That should make everything groovy.
