Overview of Microsoft Exchange 2003 Server
Microsoft Exchange 2003 Server provides a reliable, extensible, and easy-to-manage platform with round-the-clock email and team support as well as affordability. Microsoft Exchange Server 2003 supports a broad array of team activities, such as group scheduling abilities, discussion areas, and team folders, and also gives access to data that crosses geographic, logical, and technology barriers with features such as Instant Messaging (IM), real-time data, and video conferencing. Microsoft Exchange 2003 Server incorporated enhancements over Exchange Server 2000 in important technologies that address security, performance, and mobility.

Microsoft has terminated support for Exchange Server 2003, forcing network managers deal with all the problems associated with maintaining an end-of-life messaging platform. Despite this, many Exchange users are currently operating Microsoft Exchange Server 2003. Progent's Microsoft-authorized network consultants offer in-depth experience supporting Microsoft Exchange Server 2003 and can help your business to administer and repair your current Exchange Server 2003 solution or assist you to design and carry out an affordable migration to an up-to-date version of Exchange. (See Progent's Exchange 2016 upgrade support and Microsoft Exchange 2013 expertise.)

Advantages of Exchange 2003 Compared to Exchange Server 2000
Microsoft Exchange 2003 Server offers improvements in capability over MS Exchange Server 2000 in important capabilities including recovery, throughput, security, mobility, collaboration, and manageability.

  • Microsoft Exchange Server 2003 delivers enhanced recovery by including the capability of eight-node clustering, faster failover, the addition of mount points which eliminate the 24-drive designation limitation, storage area network compatibility, Volume Shadow Copy Service for backup infrastructure, a Mailbox Recovery Center utility, and a Restore Storage group.
  • MS Exchange Server 2003 enhances responsiveness via features such as /3GB and /USERVA startup switches for adjusting the allocation of memory, public folder replication improvements, distribution list performance enhancements, and suppression of Out of Office messages.
  • Security enhancements introduced by Exchange 2003 Server include IPsec compatibility for front- and back-end clusters, signed LDAP requests to Active Directory, front- and back-end Kerberos authentication, Internet Information Services (IIS) 6.0 protection, limiting of distribution lists to validated users, up-to-date Safe and Block lists, inbound recipient filtering, attachment blocking in Microsoft Outlook Web Access, and public folders permissions improvements.
  • MS Exchange Server 2003 includes better accommodation of mobile workers by adding an Outlook Web Access user interface (UI) and a more extensive feature set for Web Outlook, Microsoft Outlook speed enhancements through MAPI compression, HTTP access from Outlook, xHTML aND.htmL mobile phone browser capability, plus syncing of notifications for handheld computers.
  • Management and serviceability are simplified by organizing queues on a per-server basis, improving the user interface, revealing all system queues, controlling cookie authorization, utilizing Microsoft Exchange System Manager to transfer log files and queue data, including a multiple-client Move Mailbox feature, and adding dynamic distribution lists, public folder Send hierarchy, and public folder affinity to control referrals.

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

  • Exchange 2003 Server offers a significant increase in functionality compared to the Microsoft Exchange 5.5 web client. MS Exchange 2003 Server offers an almost complete version of the traditional Outlook GUI interface including calendaring and tools. Because of this, remote and mobile users can have full, protected access to email even without a notebook. All mobile users need is an Internet-attached computer with a conventional browser.
  • Unlike Exchange 5.5 Server, which uses its own directory, Microsoft Exchange 2003 Server takes advantage of Microsoft Active Directory, representing a more simplified administration and security structure. This makes Microsoft Exchange 2003 Server simpler to administer and maintain and also allows better protection.
  • Microsoft Exchange Server 2003 has a powerful foundation for transparently integrating third-party utilities such as anti-virus and anti-spamming tools. MS Exchange Server 2003's versatile API does away with the instability associated with Microsoft Exchange Server 5.5 when adding third-party software.
  • Exchange 2003 Server delivers significantly increased capacity and speed in comparison to MS Exchange 5.5. Enhancements allow more and larger mailboxes and speedier offsite connectivity.
  • Exchange 2003 Server also provides improved searching capability, making it easier and faster to find important information when you have to have it.

Advantages Microsoft Exchange 2003 Server Compared to an ISP-based or POP3 Email Environment
If your organization is now running an email environment hosted by an ISP or if you are operating your Microsoft Outlook users in POP3 mode, Microsoft Exchange 2003 Server provides a wealth of enhanced capabilities covering ease of management, performance, capacity, availability, and group support:

  • Unlike the store-and-forward model utilized by POP3 email systems, MS Exchange 2003 Server is based on a central-store model that liberates users from reliance on a specific desktop computer or laptop, reduces vulnerability to computer failure or viruses, and allows both on-line and off-line email, automatic backup, and sophisticated sharing and collaboration.
  • Microsoft Exchange Server 2003 has an array of collaboration capabilities that allow teams to maximize productivity by sharing calendaring, address books, messages, and files.
  • The versatility of Exchange Server 2003 makes it possible to integrate third-party security add-ins or accommodate wireless computers such as the RIM BlackBerry.
  • MS Exchange 2003 Server supports powerful management and monitoring utilities to confirm that your messaging system is running efficiently.
  • Exchange 2003 Server permits complete on-line backup without hurting productivity, enabling round-the-clock operation by avoiding scheduled downtime.
