In the Address Book window, select the distribution list. In the Contact Group window, go to the Contact Group tab, select Add Members, then choose the location where the contact is stored. If the contact is in your address book, choose From Outlook Contacts. If the contact isn't in your address book, select New E-Mail Contact. To add existing contacts from your Outlook Contact list, choose the contacts you want to add to the distribution list (hold Ctrl to select more than one contact), then select Members. Select OK to return to the distribution list. To add a new contact, enter a Display name and E-mail address. Select OK to return to the distribution list.
