Overview of Microsoft Exchange 2003 Server
MS Exchange 2003 Server delivers a dependable, scalable, and manageable infrastructure with 24×7 email and team support as well as quick return on investment. MS Exchange Server 2003 enables a broad range of team functions, such as group scheduling capabilities, discussion areas, and group folders, and furthermore provides access to information that crosses territorial, organizational, and technology barriers with features such as IM, on-demand data, and video conferencing. Microsoft Exchange 2003 Server introduced improvements over MS Exchange Server 2K in important areas that cover protection, speed, and remote and mobile communications.

Microsoft has ended support for Exchange 2003 Server, forcing IT managers deal with all the problems associated with supporting an end-of-life email system. Nevertheless, many Exchange sites are currently operating Microsoft Exchange Server 2003. Progent's Microsoft-authorized IT consultants have extensive backgrounds maintaining Microsoft Exchange 2003 and can assist your business to manage and troubleshoot your existing Microsoft Exchange 2003 environment or help you to design and execute an economical upgrade to an up-to-date edition of Exchange. (Refer to Progent's Exchange Server 2016 upgrade support and Microsoft Exchange 2019 expertise.)

Advantages of Exchange 2003 Over MS Exchange 2K Server
MS Exchange Server 2003 offers enhancements in capability over MS Exchange Server 2000 in key capabilities including recovery, throughput, security, mobile access, teamwork, and manageability.

  • Exchange 2003 Server delivers enhanced disaster recovery by including the capability of 8-node clustering, faster failover, the addition of mount points which eliminate the 24-drive designation limit, storage area network connectivity, Volume Shadow Copy Service for backup infrastructure, a Mailbox Recovery tool, and a Restore Storage group.
  • MS Exchange Server 2003 enhances responsiveness through features that include a /USERVA startup switch for tuning the use of memory address space, public folder store replication improvements, distribution list performance enhancements, and suppression of Out of Office notices.
  • Security improvements introduced by Exchange 2003 Server include Internet Protocol security (IPsec) support for front- and back-end clusters, signed Lightweight Directory Access Protocol (LDAP) requests to Active Directory, front-end and back-end Kerberos validation, IIS 6.0 protection, limiting of distribution lists to authenticated users, real-time Safe and Block lists, download filtering, attachment blocking in Microsoft Office Outlook Web Access (OWA), and public folders access enhancements.
  • Exchange 2003 Server offers better support for remote and mobile workers by including an Outlook Web Access (OWA) user interface (UI) and a more extensive range of capabilities for Web Outlook client, Outlook speed enhancements via MAPI compression, HTTP access from Outlook, cHTML aND.htmL smart phone browser capability, and syncing of notifications for handheld PCs.
  • Manageability and service are improved by centralizing queues on a per-server system, enhancing the user interface (UI), exposing all system queues, enabling cookie permission, using Microsoft Exchange System Manager to transfer log files, including a multi-user Move Mailbox function, and adding dynamic distribution lists, public folder Send hierarchy, and public folder affinity to control referrals.

Advantages of MS Exchange Server 2003 Compared to MS Exchange 5.5
Exchange Server 2003 offered major enhancements in capability over Exchange Server 5.5 in important areas including accessibility, ease of management, protection, reliability, scalability, and performance.

  • Exchange 2003 Server offers a significant increase in functionality over the Exchange 5.5 web client. Exchange 2003 Server provides an almost complete implementation of the older Microsoft Outlook graphical user interface including calendaring and utilities. As a result, remote and mobile workers get the advantage of complete, secure access to email even without a notebook. All they require is a web-attached PC with a standard browser.
  • Unlike MS Exchange 5.5 Server, which has its own directory, MS Exchange 2003 Server uses Microsoft Active Directory, representing a more streamlined administration and protection structure. This makes MS Exchange 2003 Server easier to administer and maintain and also offers better security.
  • Microsoft Exchange 2003 Server has a strong architecture for transparently integrating non-Microsoft utilities including virus and spam scanning tools. MS Exchange 2003 Server's versatile Application Programming Interface (API) solves the technical risk associated with MS Exchange 5.5 when adding third-party software.
  • MS Exchange Server 2003 delivers greatly improved scalability and performance in comparison to Exchange 5.5. Enhancements include more and larger mailboxes and speedier offsite access.
  • Microsoft Exchange 2003 Server also offers better search capability, making it easier and faster to retrieve vital data when you have to have it.

Advantages Exchange 2003 Server Compared to an ISP-based or POP3 Email Environment
If your business is currently running an email environment hosted by an ISP or if you are operating your Microsoft Outlook users in POP3 mode, MS Exchange 2003 Server offers a wealth of enhanced capabilities in the areas of ease of management, responsiveness, capacity, reliability, and collaboration:

  • Unlike the store-and-forward technique utilized by POP3 email systems, MS Exchange 2003 Server is based on a central-store model that liberates users from dependence on a specific PC or laptop, lowers vulnerability to hardware breakdown or virus attacks, and allows both on-line and off-line email, automatic backup, and sophisticated collaboration.
  • Exchange 2003 Server has an array of collaboration features that permit work groups to maximize productivity by sharing scheduling, address groups, correspondence, and files.
  • The versatility of Microsoft Exchange Server 2003 makes it possible to install third-party security add-ins or accommodate wireless devices such as the BlackBerry.
  • Microsoft Exchange 2003 Server supports advanced administration and tracking tools so you can verify that your email system is operating smoothly.
  • MS Exchange Server 2003 permits complete on-line backup without disrupting performance, supporting 24x7 operation by eliminating scheduled downtime.
