Define Custom Fields to be Mapped in Outlook?

[Amr]

I am trying to import data from an Excel sheet into an Outlook contacts list.

Most of the fields I have in the Excel sheet are being copied, such as Business Phone, Business Address, First Name, Family Name etc..

However I have a field called Category in my Excel sheet which is not showing up in the Outlook 'Map Custom Field' window. Can I define this field in Outlook so that Outlook will notice it in my Excel sheet?

I am using Outlook & Excel 2000.

Thanks
