Introducing Exchange 2003 Server
Microsoft Exchange Server 2003 delivers a reliable, scalable, and easy-to-manage infrastructure offering 24×7 messaging and collaboration as well as quick return on investment. Microsoft Exchange Server 2003 enables a wide range of collaborative activities, including group calendaring abilities, discussion groups, and group folders, and furthermore makes available data that crosses geographic, logical, and technology barriers with features that include IM, real-time information, and video conferencing. MS Exchange 2003 Server delivered improvements over MS Exchange Server 2000 in important technologies that cover security, performance, and remote and mobile communications.

In 2009 Microsoft terminated support for Microsoft Exchange 2003 Server, making network management face all the issues associated with supporting a legacy email platform. Nevertheless, a large number of Exchange users are still operating Exchange 2003. Progent's Microsoft-authorized information technology consultants have in-depth backgrounds maintaining Exchange Server 2003 and can assist your business to manage and troubleshoot your existing Microsoft Exchange 2003 environment or help you to design and carry out an economical upgrade to a current edition of Exchange. (Refer to Progent's Exchange Server 2016 migration planning and support and Exchange Server 2019 consulting.)

Advantages of Exchange Server 2003 Compared to Microsoft Exchange Server 2K
MS Exchange 2003 Server features improvements in functionality over Microsoft Exchange Server 2K in crucial areas including recovery, throughput, security, mobility, collaboration, and manageability.

  • MS Exchange Server 2003 delivers superior disaster recovery by including support for 8-node clustering, faster failover, support for mount points which eliminate the 24-drive designation limit, standard storage area network (SAN) compatibility, Volume Shadow Copy Service for database backup, a Mailbox Recovery tool, and a Restore Storage group.
  • Exchange 2003 Server improves performance through features that include a /USERVA startup switch for adjusting the use of memory address space, public folder replication enhancements, distribution list caching enhancements, and suppression of Out of Office notices.
  • Security enhancements introduced by MS Exchange Server 2003 include IPsec support for front-end and back-end clusters, signed LDAP requests to Active Directory, front-end and back-end Kerberos validation, Internet Information Services 6.0 protection, restriction of distribution lists to authenticated users, up-to-date Safe and Block data, inbound recipient filtering, attachment restrictions in Microsoft Outlook Web Access, and public folders permissions improvements.
  • Exchange Server 2003 offers better accommodation of remote and mobile users by including an Outlook Web Access user interface (UI) and a more extensive range of capabilities for Web Outlook client, Microsoft Outlook performance improvements via MAPI compression, HTTP access from Outlook, xHTML aND.htmL mobile phone browser capability, and syncing of notifications for Pocket PCs.
  • Management and serviceability are simplified by centralizing queues on a per-server basis, enhancing the user interface (UI), exposing all system queues, controlling cookie permission, utilizing Microsoft Exchange System Manager to transfer log files 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.

Advantages of Microsoft Exchange 2003 Vs. MS Exchange 5.5 Server
Exchange Server 2003 delivered significant enhancements in functionality over MS Exchange 5.5 in key areas affecting access, manageability, protection, stability, capacity, and performance.

  • Exchange 2003 Server offers a dramatic increase in functionality compared to the MS Exchange 5.5 web client. Exchange 2003 Server provides an almost complete version of the older Outlook interface including scheduling and utilities. As a result, mobile workers get the advantage of full, secure access to email even if they don't have a notebook. All mobile users need is an Internet-connected PC with a standard browser.
  • In contrast to Exchange 5.5 Server, which incorporates its own directory, Microsoft Exchange 2003 Server utilizes Active Directory, representing a more simplified administration and security model. This makes Microsoft Exchange Server 2003 less expensive to manage and maintain and also allows tighter protection.
  • MS Exchange 2003 Server has a strong architecture for transparently adding third-party utilities such as anti-virus and anti-spamming software. Microsoft Exchange Server 2003's versatile Application Programming Interface solves the technical risk often found with Microsoft Exchange 5.5 Server when integrating independent utilities.
  • Microsoft Exchange 2003 Server delivers significantly improved capacity and speed in comparison to Exchange Server 5.5. These improvements allow more and bigger mailboxes and faster remote connectivity.
  • Microsoft Exchange 2003 Server also provides better searching ability, making it simpler and quicker to find vital information when you need it.

Benefits MS Exchange 2003 Server Vs. an ISP-based or POP3 Email Environment
If your business is now using an email system hosted by an Internet Service Provider (ISP) or if you are operating your Microsoft Outlook clients in POP3 mode, Exchange 2003 Server offers an array of enhanced capabilities in the areas of ease of management, responsiveness, capacity, reliability, and group support:

  • Unlike the store-and-forward model utilized by POP3 email systems, Microsoft Exchange 2003 Server uses a central-store architecture that liberates users from reliance on a specific desktop computer or laptop, reduces vulnerability to hardware failure or virus attacks, and permits both on-line and off-line operation, programmed backup, and advanced collaboration.
  • Exchange Server 2003 has an array of collaboration features that permit teams to maximize efficiency by sharing calendaring, address books, messages, and data.
  • The versatility of Microsoft Exchange Server 2003 allows you to install non-Microsoft security enhancements or accommodate wireless computers such as the BlackBerry.
  • MS Exchange Server 2003 works with advanced administration and tracking utilities so you can make sure your email environment is operating efficiently.
  • Exchange 2003 Server allows full on-line backup without hurting productivity, enabling round-the-clock availability by avoiding routine downtime.
