Introducing Exchange Server 2003
Microsoft Exchange 2003 Server provides a reliable, scalable, and manageable platform offering 24×7 email and collaboration plus low cost of ownership. Exchange Server 2003 enables a wide array of team activities, such as group calendaring capabilities, discussion areas, and team folders, and also gives access to information that crosses territorial, logical, and technology barriers with productivity enhancers such as Instant Messaging (IM), on-demand data, and video conferencing. Exchange Server 2003 introduced enhancements over Exchange Server 2K in key technologies that address security, performance, and mobility.

In 2009 Microsoft ended support for Exchange 2003 Server, forcing information technology management face the issues associated with supporting a legacy email platform. Nevertheless, many Exchange sites are now running Exchange Server 2003. Progent's Microsoft-certified information technology engineers offer extensive backgrounds maintaining Microsoft Exchange Server 2003 and can assist your company to manage and troubleshoot your current Exchange 2003 solution or assist you to design and execute an economical upgrade to an up-to-date version of Microsoft Exchange. (Refer to Progent's Microsoft Exchange Server 2016 migration planning and support and Microsoft Exchange 2013 consulting.)

Advantages of MS Exchange 2003 Over Microsoft Exchange 2000 Server
Exchange 2003 Server offers improvements in functionality over MS Exchange Server 2000 in crucial areas including disaster recovery, throughput, protection, mobile access, collaboration, and manageability.

  • Microsoft Exchange Server 2003 offers superior disaster recovery by including the capability of 8-node clustering, faster failover, support for mount points which eliminate the 24-drive designation limitation, storage area network connectivity, Volume Shadow Copy Service for backup infrastructure, a Mailbox Recovery tool, and a Restore Storage group.
  • Exchange 2003 Server improves performance via features such as /3GB and /USERVA startup switches for tuning the use of memory, public folder store replication enhancements, distribution list caching enhancements, and suppression of Out of Office messages.
  • Security enhancements offered by Microsoft Exchange 2003 Server include Internet Protocol security support for front-end and back-end clusters, signed Lightweight Directory Access Protocol (LDAP) requests to Microsoft Active Directory, front- 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, download filtering, attachment blocking in OWA, and public folders permissions improvements.
  • Microsoft Exchange Server 2003 includes improved support for mobile users by including an Outlook Web Access (OWA) user interface and a more extensive range of capabilities for Web Outlook, Outlook performance improvements via MAPI compression, HTTP access from Microsoft Outlook, cHTML aND.htmL smart phone browser support, and syncing of notifications for handheld computers.
  • Management and serviceability are simplified by centralizing queues on a per-server system, enhancing the user experience, revealing all system queues, enabling cookie authorization, utilizing Exchange System Manager to move log and queue data, including a multi-user Move Mailbox function, and providing dynamic distribution lists, public folder Search capabilities, and public folder affinity to manage referrals.

Improvements of MS Exchange 2003 Vs. Exchange 5.5
Microsoft Exchange Server 2003 delivered significant improvements in functionality over Microsoft Exchange Server 5.5 in key areas affecting accessibility, ease of management, security, stability, scalability, and speed.

  • Microsoft Exchange Server 2003 offers a significant increase in capability over the Microsoft Exchange 5.5 web client. Exchange 2003 Server provides an almost complete version of the older MS Outlook GUI interface that features scheduling and tools. Because of this, mobile workers have the benefit of full, protected access to email even without a notebook. All they need is an Internet-attached computer with a conventional web browser.
  • In contrast to MS Exchange 5.5, which has a built-in directory, Exchange 2003 Server utilizes Active Directory (AD), representing a more streamlined management and protection structure. This makes Microsoft Exchange 2003 Server easier to manage and maintain and in addition offers tighter protection.
  • MS Exchange Server 2003 has a powerful foundation for transparently adding third-party utilities such as virus and spam scanning software. MS Exchange Server 2003's strong API eliminates the technical risk often found with MS Exchange Server 5.5 when adding independent software.
  • Microsoft Exchange Server 2003 delivers significantly increased capacity and speed in comparison to MS Exchange 5.5. Enhancements include more and larger mailboxes and speedier offsite access.
  • Exchange 2003 Server also provides better searching capability, making it simpler and faster to retrieve vital data when you need it.

Advantages Microsoft Exchange Server 2003 Compared to an ISP-based or POP3 Email System
If your business is currently using an email environment hosted by an Internet Service Provider or if you are running your Microsoft Outlook clients in POP3 mode, Exchange Server 2003 provides an array of improved capabilities covering ease of management, responsiveness, size, reliability, and group support:

  • Unlike the store-and-forward model 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 susceptibility to hardware failure or virus attacks, and permits both on-line and off-line email, automatic backup, and advanced groupware.
  • Exchange Server 2003 has an array of collaboration capabilities that allow work groups to maximize productivity by sharing calendaring, address books, correspondence, and data.
  • The flexibility of Exchange 2003 Server makes it possible to integrate third-party security add-ins or support wireless computers such as the BlackBerry smartphone.
  • Microsoft Exchange 2003 Server supports powerful administration and monitoring utilities to confirm that your email environment is operating smoothly.
  • Exchange 2003 Server allows full on-line archiving without hurting productivity, supporting 24x7 availability by eliminating scheduled maintenance blackouts.
