Overview of Microsoft Exchange Server 2003
Exchange Server 2003 provides a dependable, extensible, and easy-to-manage infrastructure offering round-the-clock messaging and collaboration as well as affordability. Exchange 2003 Server supports a wide range of team activities, including group scheduling capabilities, discussion areas, and team folders, and furthermore makes available data across geographic, logical, and architectural barriers with productivity enhancers such as Instant Messaging (IM), on-demand information, and video conferencing. MS Exchange 2003 Server introduced improvements over MS Exchange Server 2K in key areas that address security, speed, and remote access.

In 2009 Microsoft terminated support for Exchange 2003 Server, forcing information technology managers face the issues involved in supporting a legacy email system. Still, many Exchange sites are currently operating Exchange Server 2003.

Advantages of Microsoft Exchange Server 2003 Vs. MS Exchange Server 2000
MS Exchange 2003 Server offers improvements in capability over MS Exchange Server 2K in crucial areas including recovery, performance, protection, mobile access, collaboration, and simplicity of management.

  • MS Exchange Server 2003 offers enhanced recovery by adding support for eight-node clustering, faster failover, the addition of mount points which overcome the 24-drive designation limit, standard storage area network (SAN) connectivity, Volume Shadow Copy Service for backup infrastructure, a Mailbox Recovery tool, and a Restore Storage group.
  • MS Exchange 2003 Server enhances responsiveness through features such as a /USERVA startup switch for tuning the allocation of use of memory, public folder store replication improvements, distribution list performance improvements, and suppression of Out of Office messages.
  • Security enhancements offered by Microsoft Exchange 2003 Server include Internet Protocol security (IPsec) support for front-end and back-end clusters, signed Lightweight Directory Access Protocol requests to Active Directory, front-end and back-end Kerberos validation, Internet Information Services (IIS) 6.0 security, restriction of distribution lists to authenticated users, up-to-date Safe and Block lists, inbound recipient filtering, attachment blocking in Microsoft Office Outlook Web Access (OWA), and public folders access enhancements.
  • Microsoft Exchange 2003 Server offers improved accommodation of remote and mobile users by including an Outlook Web Access (OWA) user interface and a broader feature set for Web Outlook, Outlook performance improvements via MAPI compression, HTTP access from Outlook 2003, cHTML and HTML mobile phone browser support, and synchronization of notifications for handheld PCs.
  • Manageability and service are improved by centralizing queues on a per-server system, enhancing the user experience, exposing all system queues, enabling cookie authorization, using Exchange System Manager to transfer log and queue data, including a multi-user Move Mailbox function, and providing dynamic distribution lists, public folder Send Contents, and public folder affinity to control referrals.

Advantages of MS Exchange 2003 Vs. Exchange 5.5
MS Exchange Server 2003 offered major enhancements in capability over Exchange Server 5.5 in key areas affecting accessibility, ease of management, security, reliability, scalability, and speed.

  • Exchange 2003 Server offers a dramatic increase in capability over the Exchange 5.5 web client. MS Exchange Server 2003 provides a nearly identical version of the older Microsoft Outlook graphical user interface that features scheduling and tools. Because of this, mobile users can have complete, secure access to email even without a laptop. All mobile users require is an Internet-attached PC with a conventional web browser.
  • In contrast to Exchange Server 5.5, which incorporates its own directory, Exchange 2003 Server utilizes Active Directory, representing a greatly simplified management and security structure. This makes Exchange 2003 Server simpler to administer and maintain and in addition allows tighter protection.
  • MS Exchange Server 2003 has a strong foundation for seamlessly integrating third-party applications including virus and spam scanning software. Exchange 2003 Server's versatile Application Programming Interface solves the instability associated with Exchange 5.5 when integrating third-party utilities.
  • Microsoft Exchange Server 2003 delivers significantly increased scalability and performance in comparison to MS Exchange Server 5.5. Enhancements allow more and bigger mailboxes and faster offsite access.
  • Exchange 2003 Server also provides improved search capability, making it easier and faster to retrieve important data when you need it.

Benefits MS Exchange Server 2003 Over an ISP-based or POP3 Email Environment
If your organization is now using an email system hosted by an Internet Service Provider (ISP) or if you are operating your Outlook users in POP3 mode, MS Exchange Server 2003 provides an array of improved capabilities in the areas of manageability, performance, size, availability, and collaboration:

  • In contrast to the store-and-forward technique used by POP3 email systems, Microsoft Exchange 2003 Server uses a central-store model that liberates users from dependence on a specific personal computer or notebook, reduces susceptibility to hardware failure or virus attacks, and permits both on-line and off-line email, programmed backup, and advanced groupware.
  • Microsoft Exchange Server 2003 has powerful groupware features that permit teams to increase efficiency by sharing calendaring, address groups, messages, and files.
  • The flexibility of Microsoft Exchange 2003 Server makes it possible to install third-party security add-ins or accommodate wireless devices such as the RIM BlackBerry.
  • MS Exchange 2003 Server works with powerful management and monitoring tools to confirm that your messaging environment is operating efficiently.
  • Exchange 2003 Server allows complete on-line backup without disrupting performance, enabling round-the-clock operation by avoiding scheduled maintenance blackouts.
