About Mailboxes

Mailbox-enabled users use mailboxes for sending and receiving e-mail messages. Mailboxes provide locations for mailbox-enabled objects to store e-mail messages. Use Active Directory Connector to replicate existing Exchange mailboxes to Windows contacts or users.

Mail-Enabled and Mailbox-Enabled Objects

Windows Active Directory objects can be mail-enabled or mailbox-enabled.

Mail-enabled

A mail-enabled object has an e-mail address associated with it but no mailbox, and thus it can receive messages but not send them in Exchange.

Use Active Directory Users and Computers to enable e-mail capabilities for a user, group, or contact.

Mailbox-enabled

A mailbox-enabled object is an object that has an Exchange mailbox associated with it, and thus it can both send and receive e-mail messages.

Only Windows user accounts can be mailbox-enabled.

Use Active Directory Users and Computers to enable a mailbox for a Windows user account.
