Mailboxes are the most common recipient type used by information workers in an Exchange organization. Each mailbox is associated with an Active Directory user account. The user can use the mailbox to send and receive messages, and to store messages, appointments, tasks, notes, and documents. It is the primary messaging and collaboration tool for the users in your Exchange organization. To learn more about mailboxes, see Understanding Recipients.
