Introduction to Microsoft Exchange 2003 Server
Microsoft Exchange Server 2003 delivers a dependable, extensible, and easy-to-manage infrastructure offering round-the-clock email and collaboration as well as low cost of ownership. MS Exchange 2003 Server supports a wide range of collaborative functions, such as group calendaring abilities, discussion groups, and team folders, and also gives access to information across geographic, logical, and technology barriers with productivity enhancers that include Instant Messaging, on-demand information, and video conferencing. Exchange Server 2003 introduced improvements over Microsoft Exchange 2000 Server in important areas that cover protection, speed, and remote access.
In 2009 Microsoft ended support for Exchange Server 2003, requiring IT managers face the issues involved in maintaining an end-of-life messaging system. Still, many Exchange users are now running Exchange Server 2003. Progent's Microsoft-authorized IT consultants have in-depth backgrounds maintaining Microsoft Exchange Server 2003 and can help your business to administer and troubleshoot your existing Microsoft Exchange 2003 environment or help you to design and implement an affordable upgrade to a current edition of Microsoft Exchange.

Improvements of Exchange Server 2003 Compared to Microsoft Exchange 2K Server
Microsoft Exchange 2003 Server offers enhancements in functionality over MS Exchange 2000 Server in key areas such as disaster recovery, performance, protection, mobility, collaboration, and manageability.
- Exchange 2003 Server delivers enhanced recovery by including support for 8-node clustering, faster failover, support for mount points which eliminate the 24-drive designation limit, storage area network compatibility, Volume Shadow Copy Service for database backup, a Mailbox Recovery utility, and a Restore Storage group.
- MS Exchange 2003 Server improves responsiveness through features that include a /USERVA startup switch for adjusting the allocation of use of memory, public folder store replication improvements, distribution list caching enhancements, and control of Out of Office messages.
- Security enhancements introduced by MS Exchange 2003 Server include Internet Protocol security (IPsec) compatibility for front- and back-end clusters, signed LDAP requests to Active Directory, front-end and back-end Kerberos validation, IIS 6.0 security, limiting of distribution lists to validated users, up-to-date Safe and Block data, download filtering, attachment restrictions in Outlook Web Access, and public folders access improvements.
- Microsoft Exchange 2003 Server includes improved accommodation of mobile workers by including an Outlook Web Access user interface and a more extensive range of capabilities for Web Outlook client, Outlook performance enhancements through MAPI compression, HTTP compatibility from Microsoft Outlook, xHTML and HTML mobile phone browser capability, plus syncing of notifications for handheld PCs.
- Management and serviceability are improved by organizing queues on a per-server system, enhancing the user interface (UI), exposing all system queues, controlling cookie permission, utilizing Microsoft Exchange System Manager to move log and queue data, including a multiple-client Move Mailbox function, and providing dynamic distribution lists, public folder Search capabilities, and public folder affinity to manage referrals.
Improvements of Microsoft Exchange Server 2003 Vs. Microsoft Exchange Server 5.5
Exchange 2003 Server delivered significant improvements in capability over MS Exchange Server 5.5 in important areas affecting access, manageability, protection, reliability, capacity, and speed.
- Exchange Server 2003 brings a significant increase in functionality over the MS Exchange 5.5 web client. MS Exchange Server 2003 provides a nearly identical implementation of the older MS Outlook GUI interface that features calendaring and tools. Because of this, mobile users can have complete, protected access to email even without a laptop. All they require is an Internet-connected PC with a conventional browser.
- Unlike Exchange Server 5.5, which uses its own directory, Exchange Server 2003 utilizes Microsoft Active Directory, representing a more streamlined administration and security structure. This makes Exchange 2003 Server simpler to manage and support and in addition allows tighter security.
- Exchange 2003 Server has a strong architecture for seamlessly adding third-party utilities such as anti-virus and anti-spamming tools. MS Exchange 2003 Server's versatile Application Programming Interface (API) solves the technical risk associated with Exchange 5.5 when adding independent software.
- Microsoft Exchange Server 2003 offers significantly increased scalability and speed over MS Exchange Server 5.5. Enhancements include more and larger mailboxes and speedier offsite connectivity.
- MS Exchange 2003 Server also offers improved searching capability, making it simpler and quicker to find important information when you need it.
Benefits MS Exchange 2003 Server Over an ISP-based or POP3 Email Environment
If your organization is now running an email environment hosted by an ISP or if you are operating your Microsoft Outlook clients in POP3 mode, Exchange Server 2003 offers a wealth of enhanced capabilities in the areas of ease of management, performance, size, reliability, and group support:
- Unlike the store-and-forward model used by POP3 email environments, Exchange Server 2003 is based on a central-store architecture that frees users from dependence on a specific PC or notebook, lowers susceptibility to computer failure or viruses, and allows both on-line and off-line operation, programmed backup, and advanced sharing and collaboration.
- Microsoft Exchange Server 2003 has an array of collaboration features that permit teams to improve productivity by sharing calendaring, address groups, correspondence, and files.
- The flexibility of Exchange 2003 Server makes it possible to integrate third-party security add-ins or accommodate wireless devices such as the RIM BlackBerry.
- MS Exchange Server 2003 supports advanced management and monitoring tools to make sure your email environment is operating efficiently.
- Exchange Server 2003 allows full on-line backup without hurting productivity, supporting 24x7 availability by avoiding scheduled maintenance blackouts.
