To help troubleshoot the importing of contact information into Outlook, please supply some additional information;

- What version of Outlook are you using? your information says office 2003.
- When importing, are you importing three different contact lists? I.E. one form excel, .CSV and a .TSV?
- When importing the Excel spread sheet, confirm the column title says either E-mail Address or Address 1. (Note the title column should be the first open row. this field needs to be identical to the Outlook client contact field for email addresses).

Hope this helps,
