To add names directly from e-mail messages to your address book

You can set up Outlook Express so that when you reply to a message, the people you reply to are automatically added to your address book. In addition, any time you send or receive a message in Outlook Express, you can add the recipient's or sender's name to your address book.

To add all reply recipients to your address book
  1. In Outlook Express, click the Tools menu, and then click Options.
  2. On the Send tab, click Automatically put people I reply to in my Address Book.
