Supported multi-user conferences with text chat, sound, white
boards, and video These features are now found in a separate
product called Live Communications Server 2003 M: drive - In
previous versions of Exchange Server, the drive letter M was
created on the server to provide access to the information store
Some applications require the M: drive The M: drive is disabled by
default in Exchange Server 2003 Enabled if required for a software
application Key Management Service - Both Windows 2000 Server and
Windows Server 2003 include Certificate Services, which replaces
the functionality of the Key Management ServiceThe Roles in
Exchange 2003 2 Roles (Front-End & Back-End)
A "Front-End" application is one that application users interact
with directly. A "Back-End" application or program serves
indirectly in support of the front-end services, usually by being
closer to the required resource or having the capability to
communicate with the required resource. Exchange 2003

Exchange Server 2007 MicrosoftExchange Server 2007 is the next
version of Microsoft Exchange. Microsoft Exchange is the industrys
leading E-Mail, Calendaring, and Unified Messaging Server. The
release of Exchange Server 2007 is closely aligned with the 2007
Microsoft Office release. Together, these products deliver a
best-in-class enterprise messaging and collaboration solution.
Exchange 2007 introduces a new concept to Exchange organizations,
the concept of Server Roles. Features of Exchange Server 2007 It
Runs at 64-bit More Memory and Large cache. Large, Low-Cost
Mailboxes with 64-Bit Reduce I/O per sec required by 70 percent A
quarter of the disk Four times more users Larger inboxes High
Availability at Lower Cost Log shipping Reduce the need to restore
Reduce impact of backup operations Dumpster interval increased
Exchange 2007 RTM and Exchange 2007 SP1 includes the following
built-in features that can provide quick recovery, high
availability, and site resilience for Exchange 2007 Mailbox
servers: Local Continuous Replication (LCR) - LCR is a
single-server solution that uses built-in asynchronous log shipping
technology to create and maintain a copy of a storage group on a
second set of disks that are connected to the same server as the
production storage group. LCR provides log shipping, log replay,
and a quick manual switch to a secondary copy of the data.LCR is
designed to reduce the total cost of ownership for
MicrosoftExchange Server 2007 by: Reducing the recovery time for
data-level disasters by enabling a quick switch to a second online
copy of the data. Reducing the number of regular full backups that
are required for data protection. Data backups are critical to have
when a disaster strikes. Although LCR does not eliminate the need
to take backups, it does significantly reduce the need to take
regular, daily full backups. Enabling you to offload Volume Shadow
Copy Service (VSS) backups from the active copy of a storage group
to the passive copy of the storage group. All four VSS backup types
(full, copy, incremental, and differential) can be taken from the
passive copy., Offloading the backups from the active copy to the
passive copy preserves valuable disk input/output (I/O) on the
active copy's logical unit numbers (LUNs). Cluster Continuous
Replication (CCR) - CCR, which is a non-shared storage failover
cluster solution, is one of two types of clustered mailbox server
(CMS) deployments available in Exchange 2007. CCR is a clustered
solution (referred to as a CCR environment) that uses built-in
asynchronous log shipping technology to create and maintain a copy
of each storage group on a second server in a failover cluster. CCR
is designed to be either a one or two data center solution,
providing both high availability and site resilience. CCR is very
different from clustering in previous versions of Exchange Server.
CCR is designed to provide high availability for Exchange 2007
Mailbox servers by providing a solution that: Has no single point
of failure. Has no special hardware requirements. Has no shared
storage requirements. Can be deployed in one or two datacenter
configurations. Can reduce full backup frequency, reduce total
backed up data volume, and shorten the service level agreement
(SLA) for recovery time from first failure.The Key Facts about CCR
are as follows: Continuous replication is asynchronousLogs are not
copied until they are closed and no longer in use by the Mailbox
server. This means that the passive node usually does not have a
copy of every log file that exists on the active node. Continuous
replication places almost no CPU and input/output (I/O) load on the
active node during normal operationCCR uses the passive node to
copy and replay the logs. Logs are accessed by the passive node via
a secured file share. Active and passive node changes over the
lifetime of the cluster are designated automaticallyFor example,
after a failover, the active and passive designation reverses. This
means the direction of replication reverses. No administrative
action is required to reverse the replication. The system manages
the replication reversal automatically. Failover and scheduled
outages are symmetric in function and performanceFor example, it
takes just as long to fail over from Node1 to Node2 as it does to
fail over from Node2 to Node1. Typically, this would be under two
minutes. On larger servers, scheduled outages typically would be
less than four minutes. The time difference between a failover and
scheduled outages is associated with the time it takes to do a
controlled shutdown of the active node on a scheduled outage. This
performance difference may be reduced in a future service pack.
Volume Shadow Copy Service (VSS) backups on the passive node are
supportedThis allows administrators to offload backups from the
active node and extend the backup window. For example, the active
node has to respond to client requests in a timely way. A longer
backup window can be used, because the passive node has no
real-time response constraints, thereby allowing for larger
databases and larger mailbox sizes. Total data on backup media is
reducedThe CCR passive copy provides the first line of defense
against corruption and data loss. Thus, a double failure is
required before backups are needed. Recovery from the first failure
can have a relatively short SLA because no restore is required.
Recovery from the second failure can have a much longer SLA. As a
result, backups can be done on a weekly full cycle with a daily
incremental backup strategy. This reduces the total volume of data
that must be placed on the backup media. CCR can be combined with
standby continuous replication (SCR)CCR can be combined with SCR to
replicate storage groups locally in a primary data center (using
CCR for high availability) and remotely in a secondary or backup
datacenter (using SCR for site resilience). The secondary
datacenter could contain a passive node in a failover cluster that
hosts the SCR targets. This type of cluster is called a standby
cluster because it does not contain any clustered mailbox servers,
but it can be quickly provisioned with a replacement clustered
mailbox server in a recovery scenario. CCR Core Architecture
combines the following elements: Failover and virtualization
features provided by Microsoft failover clusters A majority-based
failover cluster quorum model that uses a file share as a witness
for cluster activity Transaction log replication and replay
features in Exchange 2007 Message queue feature of the Hub
Transport server called the transport dumpster AutoDiscover It
service uses a user's e-mail address or domain account to
automatically configure the user's profile. By using the e-mail
address or domain account, the Auto discover service provides the
following information to the client computer that is running
Outlook 2007: The users display name. Separate connection settings
for internal and external connectivity. The location of the users
Exchange 2007 server that has the Mailbox server role installed.
The URLs for Exchange features such as free/busy information, UM,
and the OAB. Outlook Anywhere server settings. Outlook Anywhere was
formerly known as RPC over HTTP.How the Auto Discover Service
WorksWhen you install the Client Access server role on a computer
that is running Exchange 2007, a new virtual directory named Auto
discover is created under the default Web site in Internet
Information Services (IIS). This virtual directory handles Auto
discover service requests from Outlook 2007 clients and supported
mobile devices in the following circumstances: When a new user
account is configured or updated. When a user periodically checks
for changes to the Exchange Web Services URLs. When underlying
network connection changes occur in your Exchange messaging
environment. Miscellaneous Features- includes Auto-Complete,
Conversation View, Fast search, Notifications
Roles of Exchange Server 2007Perimeter Must be run on a
workgroup based. Edge Transport perimeter mail gateway server for
hygiene and security (Filters Inbound/ Outbound traffic). Intranet
- All runs on Domain based. Client Access provides the other
mailbox server protocol access apart from MAPI. Similar to Exchange
2003 Frontend server, it enables user to use an Internet browser
(OWA), 3rd party mail client (POP3/IMAP4) and mobile device
(ActiveSync) to access their mailbox. Hub Transport handles mail
routing to next hop and Filters e-mail between mailboxes, even if
they reside on the same server. Mailbox used for storing end users
mails and public folders data. Messaging enables end users to
access their mailbox, address book, & calendar using telephone
& voice

IntegrationThe End of Support Exchange Server 2007Basically,
main-line support for Exchange 2007 with no service packs is over
with. MS continues to provide main-line support for installations
with more recent service packs for 5 years after the service pack
is introduced. After that, they enter extended support, where you
can get security updates and whatnot, but there will be no further
changes to that particular version of the Software. Exchange 2007
SP3 was released in June 2010, and is likely the last service pack
for Exchange 2007, so main line support for the product will
continue until June 2015. It will still be possible to get some
support from Microsoft for Exchange 2007 SP3 until 2020, but only
if you pay for it. After that, no support will be available other
than self-help from online sources. Exchange 2003 is EOL (meaning
no more support whatsoever) in 2015. But is already off of
Mainstream support for all service packs, but 2007 still has a few
good years left in it.
