Introduction to Microsoft Exchange Server 2003
Exchange Server 2003 delivers a reliable, extensible, and manageable platform with round-the-clock email and team support plus quick return on investment. Exchange Server 2003 enables a broad array of collaborative functions, such as group calendaring abilities, discussion areas, and group folders, and also makes available information that crosses geographic, logical, and architectural divisions with features such as Instant Messaging (IM), real-time data, and video conferencing. Microsoft Exchange 2003 Server delivered enhancements over Exchange 2K Server in important areas that address protection, speed, and remote and mobile communications.

In 2009 Microsoft terminated support for Exchange 2003 Server, making IT managers face all the issues involved in maintaining a legacy messaging system. Still, many Exchange sites are currently running Microsoft Exchange 2003. Progent's Microsoft-certified IT engineers have extensive backgrounds supporting Microsoft Exchange Server 2003 and can help your organization to administer and repair your current Microsoft Exchange Server 2003 environment or help you to design and execute an economical migration to an up-to-date version of Microsoft Exchange. (Refer to Progent's Exchange Server 2016 migration planning and support and Exchange Server 2013 consulting.)

Advantages of Exchange Server 2003 Vs. Microsoft Exchange 2K Server
Exchange Server 2003 features enhancements in capability over Microsoft Exchange 2000 Server in key areas including disaster recovery, performance, security, mobile access, collaboration, and manageability.

  • MS Exchange Server 2003 enhances responsiveness via features such as /3GB and /USERVA startup switches for adjusting the use of memory, public folder replication enhancements, distribution list caching enhancements, and control of Out of Office messages.
  • Security improvements offered by MS Exchange Server 2003 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 6.0 protection, restriction of distribution lists to authenticated users, up-to-date Safe and Block lists, download filtering, attachment restrictions in Microsoft Outlook Web Access, and public folders permissions improvements.
  • MS Exchange 2003 Server offers better support for remote and mobile workers by including an Outlook Web Access user interface (UI) and a more extensive range of capabilities for Web Outlook client, Outlook performance enhancements through MAPI compression, HTTP compatibility from Outlook 2003, xHTML aND.htmL mobile phone browser capability, and syncing of notifications for handheld computers.
  • Manageability and service are simplified by centralizing queues on a per-server system, improving the user experience, exposing all system queues, controlling cookie authorization, utilizing Exchange System Manager to move log files and queue data, including a multi-user Move Mailbox function, and adding dynamic distribution lists, public folder Search capabilities, and public folder affinity to manage referrals.

Improvements of Exchange 2003 Compared to Exchange Server 5.5
MS Exchange 2003 Server offered major improvements in capability over Exchange 5.5 in important areas including access, ease of management, security, reliability, capacity, and speed.

  • MS Exchange Server 2003 brings a significant improvement in functionality compared to the Microsoft Exchange 5.5 web client. Microsoft Exchange 2003 Server provides a nearly identical implementation of the traditional MS Outlook graphical user interface including scheduling and tools. Because of this, mobile users can have full, protected access to email even without a notebook. All mobile users require is a web-attached PC with a standard web browser.
  • Unlike Exchange 5.5 Server, which has a built-in directory, Exchange 2003 Server utilizes Active Directory (AD), providing a more simplified management and protection model. This makes Exchange 2003 Server easier to manage and support and in addition offers better protection.
  • Exchange Server 2003 has a powerful architecture for seamlessly integrating non-Microsoft applications such as virus and spam scanning software. MS Exchange Server 2003's strong Application Programming Interface (API) eliminates the instability often found with MS Exchange 5.5 Server when adding independent software.
  • MS Exchange Server 2003 offers greatly increased scalability and speed in comparison to Exchange 5.5 Server. Enhancements allow more and larger mailboxes and speedier offsite access.
  • Exchange 2003 Server also offers improved search ability, making it easier and quicker to retrieve vital information when you have to have it.

Advantages Exchange 2003 Server Vs. an ISP-provided or POP3 Email System
If your business is now running an email system hosted by an Internet Service Provider (ISP) or if you are operating your Outlook clients in POP3 mode, Exchange 2003 Server provides an array of improved features covering ease of management, performance, size, availability, and group support:

  • In contrast to the store-and-forward technique used by POP3 email systems, MS Exchange 2003 Server uses a central-store architecture that frees users from dependence on a specific desktop computer or notebook, reduces susceptibility to computer breakdown or virus attacks, and permits both on-line and off-line email, programmed backup, and advanced sharing and collaboration.
  • MS Exchange 2003 Server offers an array of collaboration features that allow work groups to increase efficiency by sharing calendaring, address books, messages, and data.
  • The versatility of Exchange Server 2003 makes it possible to install third-party security add-ins or support wireless computers such as the BlackBerry.
  • MS Exchange Server 2003 supports advanced administration and tracking tools so you can make sure your email system is operating efficiently.
  • Exchange Server 2003 allows full on-line backup without hurting performance, enabling 24x7 availability by eliminating scheduled maintenance blackouts.
