Exchange Server 2007 Recipient Objects
Exchange Server 2007 contains Recipients that are either mailbox - enabled or mail - enabled.
A user mailbox is a mailbox - enabled Recipient object with an Exchange Server 2007 mailbox. This
mailbox houses several types of data such as email messages, contacts, calendar items, tasks, and other
documents. This Recipient object is associated with a single Enabled Active Directory Services user object.
A user mailbox can be converted to a shared mailbox or resource mailbox and vice versa. Mailbox type
conversion can only be accomplished through the Exchange Management Shell. To perform this
procedure, the Active Directory User account must be granted the Exchange Recipient Administrator role.
Using the Get-Recipient or Get-Mailbox cmdlets returns user mailboxes in the organization. This
object has a Recipient type of UserMailbox .
