Introducing Exchange Server 2003
Exchange Server 2003 provides a dependable, scalable, and manageable platform with round-the-clock messaging and team support plus quick return on investment. Microsoft Exchange Server 2003 supports a broad array of collaborative functions, including group scheduling abilities, discussion groups, and team folders, and also gives access to information that extends over geographic, organizational, and architectural barriers with productivity enhancers such as Instant Messaging, on-demand information, and video conferencing. Microsoft Exchange Server 2003 introduced enhancements over MS Exchange 2K Server in key technologies that address protection, speed, and remote access.

Microsoft has terminated support for Microsoft Exchange 2003 Server, making network management deal with all the issues involved in maintaining an end-of-life email platform. Despite this, a large number of Exchange sites are now operating Exchange 2003. Progent's Microsoft-certified IT engineers have in-depth experience supporting Exchange Server 2003 and can assist your company to manage and repair your existing Microsoft Exchange 2003 environment or help you to plan and carry out an affordable upgrade to a current edition of Microsoft Exchange. (See Progent's Microsoft Exchange Server 2016 upgrade support and Microsoft Exchange 2013 expertise.)

Advantages of Microsoft Exchange 2003 Over MS Exchange 2000 Server
Exchange 2003 Server offers enhancements in functionality over MS Exchange Server 2K in key capabilities such as disaster recovery, throughput, security, mobile access, collaboration, and simplicity of management.

  • Exchange 2003 Server offers superior disaster recovery by adding the capability of eight-node clustering, faster failover, the addition of mount points which eliminate the 24-drive letter limitation, SAN compatibility, Volume Shadow Copy Service for database backup, a Mailbox Recovery Center utility, and a Restore Storage group.
  • MS Exchange 2003 Server enhances performance via innovations that include /3GB and /USERVA startup switches for tuning the use of memory, public folder replication improvements, distribution list performance improvements, and suppression of Out of Office messages.
  • Security improvements introduced by MS Exchange Server 2003 include 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 security, limiting of distribution lists to authenticated users, real-time Safe and Block data, inbound recipient filtering, attachment restrictions in OWA, and public folders access enhancements.
  • MS Exchange 2003 Server offers better support for mobile users by adding an Outlook Web Access user interface and a more extensive feature set for Web Outlook, Microsoft Outlook speed enhancements via MAPI compression, HTTP access from Outlook, cHTML aND.htmL mobile phone browser support, plus synchronization of notifications for handheld computers.
  • Manageability and serviceability are simplified by centralizing queues on a per-server system, improving the user interface (UI), exposing all system queues, enabling cookie permission, using Exchange System Manager to move log files and queue data, including a multiple-client Move Mailbox function, and providing dynamic distribution lists, public folder Send Contents, and public folder affinity to manage referrals.

Improvements of MS Exchange Server 2003 Compared to Exchange Server 5.5
MS Exchange 2003 Server offered significant enhancements in functionality over Microsoft Exchange 5.5 Server in important areas affecting accessibility, ease of management, security, stability, capacity, and performance.

  • Microsoft Exchange Server 2003 brings a significant improvement in functionality compared to the MS Exchange 5.5 web client. Microsoft Exchange 2003 Server offers a nearly identical implementation of the traditional MS Outlook interface that features calendaring and utilities. As a result, remote and mobile workers can have complete, secure access to email even without a notebook. All mobile users require is a web-attached computer with a conventional web browser.
  • Unlike Exchange 5.5 Server, which incorporates its own directory, Exchange 2003 Server takes advantage of Active Directory (AD), providing a more streamlined administration and security structure. This makes Exchange Server 2003 simpler to manage and support and also allows better protection.
  • Microsoft Exchange Server 2003 has a strong foundation for seamlessly integrating non-Microsoft applications including virus and spam scanning tools. Exchange Server 2003's strong Application Programming Interface solves the technical risk associated with MS Exchange Server 5.5 when adding independent software.
  • Exchange Server 2003 delivers greatly improved scalability and performance over MS Exchange 5.5. Improvements include more and larger mailboxes and faster remote access.
  • MS Exchange 2003 Server also provides better searching capability, making it simpler and faster to find important data when you need it.

Benefits Exchange Server 2003 Compared to an ISP-provided or POP3 Email System
If your organization is now running an email environment hosted by an Internet Service Provider (ISP) or if you are running your Microsoft Outlook clients in POP3 mode, MS Exchange 2003 Server offers a wealth of improved features covering ease of management, performance, size, availability, and group support:

  • In contrast to the store-and-forward model utilized by POP3 email environments, Microsoft Exchange Server 2003 uses a central-store architecture that liberates users from reliance on a specific PC or laptop, reduces vulnerability to computer breakdown or viruses, and allows both on-line and off-line email, automatic backup, and sophisticated sharing and collaboration.
  • MS Exchange 2003 Server offers an array of groupware capabilities that permit work groups to increase productivity by sharing calendaring, address groups, messages, and files.
  • The versatility of MS Exchange Server 2003 makes it possible to install non-Microsoft security enhancements or support wireless devices such as the RIM BlackBerry.
  • Microsoft Exchange Server 2003 supports powerful management and monitoring utilities so you can confirm that your messaging environment is running smoothly.
  • Microsoft Exchange 2003 Server allows complete on-line backup without hurting performance, supporting round-the-clock operation by eliminating scheduled downtime.
