A distribution list is a collection of contacts. It provides an easy way to send messages to a group of people. For example, if you frequently send messages to the marketing team, you can create a distribution list named Marketing Team that contains the names of all members of this team. A message sent to this distribution list goes to all recipients who belong to the list. Outlook 2007 converts the address list to individual addresses, so recipients see their own names and the names of all other recipients in the To box of the message instead of seeing the name of the distribution list. You can use distribution lists in messages, task requests, and meeting requests.
