Microsoft® Exchange Server 2007 setup displays this warning because an existing Hub Transport server role couldn't be detected in the local Active Directory® directory service site.

You have chosen to install the Mailbox Server role before an instance of the Hub Transport role is installed in the Active Directory site.

Exchange 2007 Hub Transport Services is deployed inside your organization's Active Directory. Hub Transport Services handles all mail flow inside the organization, applies organizational mail flow routing rules, and is responsible for delivering messages to a recipient's mailbox.

Users are able to sign-in their mailboxes, but mail can't be sent or received from this mailbox server until a Hub Transport role is installed.
