Overview of Microsoft Exchange 2003 Server
Microsoft Exchange 2003 Server delivers a reliable, extensible, and manageable infrastructure with 24×7 email and team support as well as low cost of ownership. Microsoft Exchange Server 2003 enables a broad array of collaborative functions, such as group calendaring abilities, discussion areas, and team folders, and furthermore provides access to data that extends over territorial, organizational, and technology divisions with features that include IM, real-time information, and video conferencing. MS Exchange 2003 Server delivered enhancements over Exchange Server 2K in key areas that cover security, performance, and mobility.

In 2009 Microsoft terminated support for Microsoft Exchange 2003 Server, making network management deal with all the problems associated with supporting a legacy messaging platform. Nevertheless, many Exchange users are currently running Exchange Server 2003. Progent's Microsoft-certified information technology consultants offer in-depth experience supporting Exchange 2003 and can assist you to administer and repair your existing Exchange 2003 environment or help you to design and execute an affordable upgrade to a current version of Microsoft Exchange. (Refer to Progent's Microsoft Exchange 2016 migration planning and support services and Microsoft Exchange Server 2013 expertise.)

Advantages of MS Exchange Server 2003 Compared to MS Exchange 2000 Server
MS Exchange 2003 Server features improvements in functionality over MS Exchange Server 2000 in crucial capabilities such as disaster recovery, throughput, protection, mobile access, teamwork, and manageability.

  • MS Exchange 2003 Server offers improved recovery by including support for eight-node clustering, quicker cluster failover, the addition of mount points which overcome the 24-drive designation limitation, 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 performance via features that include a /USERVA startup switch for adjusting the allocation of use of memory, public folder replication improvements, distribution list caching improvements, and control of Out of Office messages.
  • Security enhancements offered by Exchange Server 2003 include IPsec compatibility for front- and back-end clusters, signed LDAP requests to Active Directory, front-end and back-end Kerberos validation, Internet Information Services (IIS) 6.0 security, limiting of distribution lists to validated users, up-to-date Safe and Block data, inbound recipient filtering, attachment blocking in OWA, and public folders access improvements.
  • MS Exchange Server 2003 offers better accommodation of remote and mobile workers by including an Outlook Web Access user interface and a broader range of capabilities for Web Outlook, Outlook performance enhancements through MAPI compression, HTTP access from Microsoft Outlook, xHTML aND.htmL mobile phone browser support, and syncing of notifications for handheld PCs.
  • Manageability and serviceability are improved by organizing queues on a per-server system, enhancing the user interface (UI), exposing all system queues, enabling cookie authorization, utilizing Exchange System Manager to transfer log and queue data, including a multi-user Move Mailbox feature, and providing dynamic distribution lists, public folder Search capabilities, and public folder affinity to manage referrals.

Improvements of Microsoft Exchange 2003 Vs. Microsoft Exchange 5.5
Exchange Server 2003 offered major enhancements in capability over Microsoft Exchange 5.5 in important areas including access, ease of management, protection, stability, capacity, and speed.

  • Exchange Server 2003 brings a significant increase in functionality over the Exchange 5.5 web client. MS Exchange 2003 Server offers a nearly identical version of the traditional MS Outlook graphical user interface that features scheduling and utilities. Because of this, mobile users get the advantage of complete, secure access to email even without a notebook. All they need is a web-attached computer with a standard web browser.
  • Unlike Microsoft Exchange 5.5 Server, which incorporates its own directory, Microsoft Exchange 2003 Server uses Active Directory (AD), providing a more streamlined administration and protection model. This makes Exchange 2003 Server simpler to manage and maintain and in addition allows tighter security.
  • MS Exchange 2003 Server has a strong architecture for seamlessly integrating non-Microsoft applications such as virus and spam scanning software. Exchange Server 2003's versatile API does away with the technical risk associated with Microsoft Exchange 5.5 when integrating independent software.
  • Microsoft Exchange 2003 Server offers greatly increased capacity and performance over Microsoft Exchange 5.5 Server. Improvements include more and larger mailboxes and speedier offsite access.
  • MS Exchange Server 2003 also provides better search capability, making it easier and faster to retrieve vital information when you need it.

Benefits MS Exchange 2003 Server Over an ISP-provided or POP3 Email Environment
If your business is now using an email system hosted by an Internet Service Provider (ISP) or if you are running your Outlook users in POP3 mode, Exchange 2003 Server offers a wealth of enhanced features covering manageability, performance, size, reliability, and collaboration:

  • Unlike the store-and-forward model used by POP3 email systems, MS Exchange 2003 Server uses a central-store architecture that liberates users from reliance on a specific personal computer or notebook, lowers vulnerability to hardware failure or viruses, and allows both on-line and off-line email, programmed backup, and sophisticated groupware.
  • Microsoft Exchange 2003 Server has an array of collaboration features that permit teams to improve efficiency by sharing calendaring, address groups, messages, and data.
  • The flexibility of MS Exchange Server 2003 allows you to integrate non-Microsoft security add-ins or accommodate wireless devices such as the BlackBerry.
  • Microsoft Exchange 2003 Server works with advanced administration and tracking tools so you can make sure your messaging environment is running efficiently.
  • Microsoft Exchange Server 2003 allows full on-line archiving without hurting productivity, enabling round-the-clock availability by avoiding scheduled downtime.
