Address Magic Personal Edition - description from Softdepia.com:
Address Magic Personal Edition helps you to quickly import your email address book from one email application to another. For example, if you have decided to use the Netscape email application instead of Outlook Express, the Personal Edition will copy the address book from Outlook Express to Netscape. Address Magic Personal Edition simplifies this process by automatically identifying the address books you already have installed and automatically finding their location. The Personal Edition's three-step wizard allows you to quickly and easily complete your conversion.
Address Magic Personal Edition is a "Free to try" program. You can download and try it for an evaluation period.
