It is the major update to the Exchange server messaging system Exchange server 2003 and Active Directory 2003 provided a more reliable experience, better performance, and integration support between Exchange server and AD. Added Mobility access feature for users to synchronize their Mobile Devices to Exchange server. Mirroring in the OWA interface with the normal Microsoft office Outlook Desktop client, so users can operate easily. Windows Server 2003 introduced Clustering service, which helps to MS Exchange server 2003, and also supports Active and Active-Passive clustering.Features of Exchange Server 2003

Active Directory Integration - Directory service for tracking user characteristics and system configuration Cluster Capable - Allows applications to be installed on multiple servers but running on only one at a time If an application fails on one server, a second server takes over. Important for highly available systems Policy-Based Management Recipient Policies - Allow administrators to define criteria for groups of users to be managed Server Policies - Used to manage groups of servers Recipient Management Flexibility Potential recipients: Users (most common) Security groups Distribution groups Contacts Public folder

Excellent Client Software - Exchange Server 2003 is capable of acting as a server for many different e-mail clients. Outlook Web Access (OWA)- A Web-based version of Outlook Simple Mail Transfer Protocol (SMTP) - For mail delivery Post Office Protocol version 3 (POP3)- Allows storage of messages in a single inbox Internet Message Access Protocol (IMAP) - Allows message storage in multiple folders Address Book Manageability Global Address List (GAL)- List of all users in an organization Application Service Provider (ASP) - Ensures that each customer only has his own employees in the GAL Public Folders - are used by Exchange Server 2003 to support: Shared calendars Discussion groups Shared mailboxes Messaging applications

Scalability - Scaling Out a single application is installed on multiple servers. Servers communicate to operate as a single system Security - is supported when users are sending messages Secure Multipurpose Internet Mail Extension (S/MIME) - Encrypts Internet e-mail messages Secure Sockets Layer (SSL)- Encrypts communication between servers and clients Disaster Recovery NT Backup is installed with Exchange Server 2003 Backs up the Exchange databases while being accessed Backs up and restores only entire Exchange databases Third-party software can restore individual messages Flexible Upgrade Options Exchange Server 5.5 and Exchange 2000 Server can be upgraded to Exchange Server 2003 Exchange 2000 Server can be upgraded with a simple in-place upgrade Exchange Server 2003 is installed over an existing Exchange 2000 server Volume Shadow Copy Service - It enable improved backup and restore capabilities, thereby reducing the impact to users and increasing system availability.New Features of Exchange Server 2003 Improved Outlook Web Access (OWA) - The new version of OWA has almost the complete functionality of the full Outlook client Attachment blocking stops attachments with certain file extensions Junk e-mail filtering moves junk mail out of the main inbox and into a junk mail folder S/MIME allows OWA users to send encrypted e-mail Kerberos Authentication - The standard authentication protocol for all versions of Windows starting with Windows 2000 Server and Professional. Provides enhanced security over the older NTLM authentication Remote Procedure Call (RPC) over Hypertext Transfer Protocol (HTTP)- Allows mobile users to use the full Outlook client. Connecting to Outlook client remotely required the use of a Virtual Private Network (VPN) connection Mobile Services for Exchange - Allows mobile users to access their information stored on Exchange Server 2003 Query-Based Distribution Groups Dynamically defines membership of a group based on a Lightweight Directory Access Protocol (LDAP) query Reduces time spent maintaining the memberships and makes lists more accurate Recovery Storage Group -used to recover individual messages. Enhanced Clustering - Exchange Server 2003 supports using up to eight servers in a cluster. Clustering support in Exchange 2000 Server only allowed for two servers in a cluster Internet Mail Wizard - Easier for administrators to configure their Exchange servers to connect with the Internet Functions controlled through the Internet Mail Wizard: E-mail domains Relaying Rules for outbound messages Connection Filtering Restricts which servers are allowed to send e-mail messages to an Exchange server Block lists provide data about IP addresses based on rules Lists configured to block incoming mail from the IP addresses Maintained by third parties and are accessible over the InternetRemoved Features in Exchange Server 2003 Connectors for Lotus ccMail and Microsoft Mail - If you require ongoing connectivity to either Lotus ccMail or Microsoft Mail, you should ensure that there is at least one Exchange 2000 server in your organization Real-Time Collaboration Features-Provided real-time collaboration for instant messaging. 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 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

It enables the coordination of meetings, appointments, contacts, and public folder information between disjointed Exchange organizations.

Policy-Based Routing - PBR gives you a flexible means of routing packets by allowing you to configure a defined policy for traffic flows, lessening reliance on routes derived from routing protocols.

Server Roles - is a set of software programs that, when they are installed and properly configured, lets a computer perform a specific function for multiple users or other computers within a network.

Filtering Include Antivirus, and Anti-Spam. It is agents works with spam confidence level rating. This rating is a number from 0-9 for each message; a high SCL will mean that it is most likely spam. You can configure the agent according to the message ratings to: Delete the message Reject the message Quarantine the message

Anti-Virus The antivirus filter allows command line virus checkers to be used on emails that as they pass through the Mail Enable server either for relay or for delivery to local mailboxes.

New for Exchange 2007: Web Services Unified Storage Access with Web services - is a storage system that makes it possible to run and manage files and applications from a single device. Outlook Interoperability provided via Exchange Business Logic Layer No Client-Side Runtime necessary Strongly Typed Objects for Messages, Calendar Items, Contacts and more Great Visual Studio .NET 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.
