After you add contacts to your Web-Based Email Address Book, you may want to group the contacts into lists, such as a list of employees or a list of customers. By grouping contacts, you create a Distribution List that makes it easy to send an email message to all contacts in a specific list at one time, without having to add the contacts individually.
To Create a Contact Distribution List
In the NOT on the distribution list box, select the contact you want to include in the list, and then click Add.
TIP: You can select multiple contacts by pressing and holding CTRL while you select the contacts.
