Overview of Microsoft Exchange Server 2003
Microsoft Exchange 2003 Server provides a dependable, scalable, and easy-to-manage infrastructure offering 247 email and team support plus affordability. MS Exchange 2003 Server supports a broad range of team activities, such as group scheduling abilities, discussion areas, and group folders, and furthermore gives access to data that crosses geographic, organizational, and technology barriers with productivity enhancers that include IM, on-demand data, and video conferencing. MS Exchange Server 2003 introduced enhancements over Exchange 2000 Server in key areas that address security, performance, and mobility.

Microsoft has terminated support for Microsoft Exchange 2003 Server, requiring IT managers deal with all the problems involved in supporting an end-of-life email platform. Despite this, a large number of Exchange users are currently running Microsoft Exchange Server 2003. Progent's Microsoft-authorized information technology consultants have extensive backgrounds maintaining Microsoft Exchange 2003 and can help your organization to administer and troubleshoot your current Exchange Server 2003 solution or assist you to design and implement an economical migration to an up-to-date version of Microsoft Exchange. (See Progent's Microsoft Exchange 2016 migration planning and support services and Exchange Server 2013 consulting.)

Improvements of Exchange Server 2003 Vs. Exchange 2K Server
Microsoft Exchange 2003 Server offers improvements in functionality over MS Exchange Server 2000 in important capabilities including recovery, throughput, protection, mobile access, teamwork, and manageability.

  • Microsoft Exchange 2003 Server delivers enhanced recovery by adding the capability of eight-node clustering, faster failover, support for mount points which eliminate the 24-drive letter limit, storage area network compatibility, Volume Shadow Copy Service for backup infrastructure, a Mailbox Recovery utility, and a Restore Storage group.
  • Microsoft Exchange Server 2003 enhances performance through innovations that include /3GB and /USERVA startup switches for adjusting the use of memory, public folder store replication improvements, distribution list performance enhancements, and suppression of Out of Office notices.
  • Security improvements offered by MS Exchange Server 2003 include Internet Protocol security compatibility for front-end and back-end clusters, signed Lightweight Directory Access Protocol requests to Active Directory, front- and back-end Kerberos authentication, IIS 6.0 protection, limiting of distribution lists to validated users, real-time Safe and Block data, inbound recipient filtering, attachment restrictions in OWA, and public folders access enhancements.
  • Microsoft Exchange Server 2003 includes better support for remote and mobile workers by including an Outlook Web Access (OWA) user interface (UI) and a broader feature set for Web Outlook, Outlook speed improvements via MAPI compression, HTTP access from Outlook, cHTML and HTML smart phone browser capability, plus synchronization of notifications for Pocket PCs.
  • Manageability and serviceability are improved by centralizing queues on a per-server system, improving the user interface (UI), exposing all system queues, enabling cookie authorization, utilizing Microsoft Exchange System Manager to move log and queue data, including a multi-user Move Mailbox function, and providing dynamic distribution lists, public folder Send Contents, and public folder affinity to control referrals.

Improvements of Exchange 2003 Over Microsoft Exchange 5.5
Microsoft Exchange 2003 Server delivered significant improvements in capability over Microsoft Exchange 5.5 Server in important areas affecting access, ease of management, security, stability, scalability, and speed.

  • MS Exchange Server 2003 offers a dramatic increase in capability compared to the Exchange 5.5 web client. Exchange Server 2003 provides an almost complete version of the traditional Outlook graphical user interface including calendaring and tools. As a result, mobile users can have complete, secure availability of email even if they don't have a laptop. All mobile users require is an Internet-attached computer with a conventional browser.
  • Unlike Microsoft Exchange Server 5.5, which uses its own directory, Exchange Server 2003 utilizes Active Directory, representing a greatly simplified administration and protection structure. This makes Exchange 2003 Server simpler to manage and maintain and in addition allows tighter security.
  • Exchange 2003 Server has a strong foundation for transparently adding third-party utilities including anti-virus and anti-spamming software. Exchange 2003 Server's strong API does away with the instability associated with Microsoft Exchange 5.5 when adding independent software.
  • Exchange Server 2003 delivers significantly increased scalability and speed over Microsoft Exchange Server 5.5. Improvements allow more and larger mailboxes and faster offsite access.
  • MS Exchange 2003 Server also offers improved search capability, making it simpler and faster to find vital data when you need it.

Advantages Microsoft Exchange Server 2003 Compared to an ISP-based or POP3 Email Environment
If your organization is currently using an email system hosted by an ISP or if you are running your Microsoft Outlook users in POP3 mode, Exchange Server 2003 provides a wealth of improved features covering ease of management, performance, capacity, availability, and collaboration:

  • Unlike the store-and-forward technique used by POP3 email environments, MS Exchange Server 2003 uses a central-store architecture that liberates users from reliance on a specific personal computer or laptop, lowers susceptibility to computer failure or virus attacks, and permits both on-line and off-line operation, automatic backup, and advanced groupware.
  • Exchange 2003 Server has an array of groupware features that permit work groups to maximize efficiency by sharing scheduling, address books, correspondence, and data.
  • The flexibility of Exchange Server 2003 allows you to integrate third-party security add-ins or support wireless devices such as the BlackBerry.
  • MS Exchange 2003 Server works with advanced management and monitoring tools so you can make sure your email environment is running efficiently.
  • Exchange 2003 Server allows full on-line archiving without hurting productivity, enabling 24x7 operation by avoiding scheduled maintenance blackouts.
