Introducing Exchange 2003 Server
Exchange Server 2003 provides a reliable, scalable, and easy-to-manage infrastructure offering 24×7 email and team support as well as quick return on investment. Exchange Server 2003 enables a broad array of team functions, including group scheduling capabilities, discussion groups, and group folders, and furthermore makes available data across territorial, logical, and architectural divisions with features that include Instant Messaging, on-demand data, and video conferencing. Exchange Server 2003 incorporated improvements over MS Exchange Server 2K in important technologies that address protection, performance, and remote and mobile communications.

Microsoft has ended support for Exchange Server 2003, forcing network managers deal with the problems involved in maintaining a legacy email platform. Still, a large number of Exchange users are now running Exchange 2003. Progent's Microsoft-certified IT consultants offer in-depth experience maintaining Exchange 2003 and can assist your business to administer and troubleshoot your current Exchange 2003 solution or help you to plan and carry out an affordable migration to an up-to-date edition of Exchange. (Refer to Progent's Microsoft Exchange 2016 migration planning and support and Exchange 2019 consulting.)

Improvements of Microsoft Exchange Server 2003 Over Microsoft Exchange 2000 Server
MS Exchange Server 2003 offers improvements in functionality over Microsoft Exchange Server 2K in crucial capabilities such as recovery, performance, security, mobility, collaboration, and simplicity of management.

  • Microsoft Exchange 2003 Server offers superior recovery by including support for eight-node clustering, faster failover, the addition of mount points which overcome the 24-drive letter limit, standard storage area network (SAN) connectivity, Volume Shadow Copy Service for database backup, a Mailbox Recovery Center tool, and a Restore Storage group.
  • MS Exchange 2003 Server enhances performance through features such as /3GB and /USERVA startup switches for tuning the allocation of use of memory address space, public folder replication enhancements, distribution list performance improvements, and suppression of Out of Office messages.
  • Security enhancements introduced by Microsoft Exchange 2003 Server include Internet Protocol security support for front-end and back-end clusters, signed Lightweight Directory Access Protocol requests to Microsoft Active Directory, front-end and back-end Kerberos validation, IIS 6.0 protection, restriction of distribution lists to authenticated users, real-time Safe and Block lists, download filtering, attachment blocking in Microsoft Outlook Web Access, and public folders permissions enhancements.
  • MS Exchange Server 2003 offers improved accommodation of mobile workers by adding an Outlook Web Access user interface and a broader feature set for Web Outlook client, Outlook speed enhancements via MAPI compression, HTTP compatibility from Outlook 2003, cHTML aND.htmL smart phone browser support, and syncing of notifications for Pocket PCs.
  • Manageability and service are simplified by organizing queues on a per-server system, improving the user experience, exposing all system queues, enabling cookie authorization, utilizing Exchange System Manager to move log files, including a multiple-client Move Mailbox feature, and providing dynamic distribution lists, public folder Send Contents, and public folder affinity to control referrals.

Improvements of Microsoft Exchange 2003 Vs. Microsoft Exchange Server 5.5
Exchange Server 2003 offered major enhancements in capability over MS Exchange 5.5 Server in key areas affecting accessibility, ease of management, protection, reliability, capacity, and speed.

  • Microsoft Exchange Server 2003 offers a significant increase in functionality compared to the Exchange 5.5 web client. Microsoft Exchange 2003 Server provides a nearly identical version of the older MS Outlook interface that features scheduling and utilities. Because of this, remote and mobile users can have full, protected access to email even without a laptop. All they require is an Internet-attached PC with a conventional browser.
  • In contrast to Exchange Server 5.5, which uses a built-in directory, Exchange 2003 Server takes advantage of Active Directory (AD), providing a more streamlined management and protection structure. This makes MS Exchange 2003 Server simpler to manage and maintain and also allows tighter protection.
  • Microsoft Exchange Server 2003 has a strong architecture for transparently integrating third-party utilities such as anti-virus and anti-spamming tools. MS Exchange Server 2003's strong API does away with the technical risk often found with Exchange 5.5 when integrating third-party software.
  • MS Exchange 2003 Server offers significantly improved scalability and performance over Exchange Server 5.5. These improvements include more and larger mailboxes and faster offsite access.
  • Microsoft Exchange 2003 Server also provides better search ability, making it easier and quicker to find important data when you need it.

Benefits 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 running your Microsoft Outlook clients in POP3 mode, Exchange Server 2003 offers a wealth of improved capabilities in the areas of ease of management, responsiveness, capacity, reliability, and group support:

  • In contrast to the store-and-forward technique used by POP3 email environments, Microsoft Exchange 2003 Server is based on a central-store architecture that liberates users from dependence on a specific desktop computer or notebook, lowers vulnerability to computer breakdown or virus attacks, and permits both on-line and off-line email, automatic backup, and advanced groupware.
  • Microsoft Exchange 2003 Server offers powerful groupware capabilities that permit teams to maximize efficiency by sharing calendaring, address books, messages, and files.
  • The flexibility of Exchange 2003 Server allows you to integrate non-Microsoft security enhancements or accommodate wireless devices such as the BlackBerry smartphone.
  • Microsoft Exchange Server 2003 works with powerful management and tracking utilities so you can confirm that your email system is running smoothly.
  • Microsoft Exchange 2003 Server permits complete on-line backup without disrupting productivity, enabling round-the-clock availability by avoiding routine maintenance blackouts.
