storage groups and databases per server.
Exchange 2007 lets you create as many as 50 storage
groups per server. Although a storage group can contain as many as
5 databases, there is a limit of 50 databases per server.

Exchange 2007 computers that are running the Hub Transport
server role are deployed in a site, mail flow between Hub Transport

not require any additional configuration by the administrator. If a
Hub Transport server (formerly known as a bridgehead server) is
unavailable because of a failure or regularly scheduled
maintenance, failover to the other Hub Transport servers is
- High availability for Mailbox
servers Exchange 2007 includes three
built-in features that provide high availability for Mailbox
servers: Local continuous replication (LCR), cluster continuous
replication (CCR), and single copy clusters (SCC). The continuous
replication features use log shipping to create a second copy of a
production storage group. In an LCR environment, the second copy is
located on the same server as the production storage group. In a
CCR environment, the second copy is located on the passive node in

commercial e-mail, at the network perimeter.
- Autodiscover To optimize bandwidth,
when a remote user connects to an Exchange 2007 computer that
has the Client Access server role installed, the Client Access
server that accepts the initial request locates the user's mailbox.
After the user's Mailbox server is located, the client request is
redirected to the Client Access server that is nearest to the
user's Mailbox server.
