Overview of Exchange Server 2003
Exchange Server 2003 delivers a dependable, scalable, and manageable infrastructure offering 247 email and team support plus low cost of ownership. Exchange 2003 Server supports a broad array of team functions, including group scheduling capabilities, discussion groups, and group folders, and also makes available data that extends over geographic, organizational, and architectural barriers with productivity enhancers that include Instant Messaging, real-time data, and video conferencing. MS Exchange Server 2003 incorporated enhancements over MS Exchange 2K Server in important areas that cover security, speed, and remote access.

In 2009 Microsoft ended support for Exchange 2003 Server, requiring information technology managers deal with all the problems associated with supporting a legacy email platform. Nevertheless, many Exchange sites are now operating Microsoft Exchange 2003. Progent's Microsoft-certified network engineers have extensive experience maintaining Microsoft Exchange Server 2003 and can assist your business to administer and troubleshoot your current Exchange 2003 solution or assist you to plan and execute an economical migration to a current version of Exchange.

Advantages of Exchange 2003 Compared to Microsoft Exchange 2000 Server
MS Exchange Server 2003 features enhancements in capability over Microsoft Exchange Server 2000 in crucial areas including recovery, performance, security, mobility, teamwork, and simplicity of management.

  • MS Exchange Server 2003 delivers improved disaster recovery by including support for eight-node clustering, faster failover, support for mount points which overcome the 24-drive designation limitation, SAN compatibility, Volume Shadow Copy Service for database backup, a Mailbox Recovery utility, and a Restore Storage group.
  • MS Exchange Server 2003 enhances responsiveness via features that include a /USERVA startup switch for tuning the allocation of memory and memory address space, public folder store replication improvements, distribution list caching improvements, and suppression of Out of Office messages.
  • Security enhancements offered by Exchange 2003 Server include Internet Protocol security support for front- and back-end clusters, signed Lightweight Directory Access Protocol requests to Microsoft Active Directory, front-end and back-end Kerberos validation, Internet Information Services (IIS) 6.0 protection, limiting of distribution lists to validated users, real-time Safe and Block data, download filtering, attachment restrictions in OWA, and public folders permissions enhancements.
  • MS Exchange 2003 Server offers improved support for remote and mobile workers by including an Outlook Web Access (OWA) user interface (UI) and a more extensive feature set for Web Outlook, Outlook performance enhancements through MAPI compression, HTTP compatibility from Microsoft Outlook, xHTML and HTML mobile phone browser support, and synchronization of notifications for handheld computers.
  • Management and service are simplified by centralizing queues on a per-server basis, enhancing the user experience, exposing all system queues, enabling cookie permission, utilizing Exchange System Manager to move log files and queue data, including a multi-user Move Mailbox feature, and adding dynamic distribution lists, public folder Search capabilities, and public folder affinity to manage referrals.

Advantages of MS Exchange Server 2003 Vs. MS Exchange Server 5.5
MS Exchange Server 2003 offered major improvements in functionality over MS Exchange 5.5 Server in important areas affecting access, ease of management, security, reliability, scalability, and performance.

  • Microsoft Exchange 2003 Server brings a significant increase in capability compared to the MS Exchange 5.5 web client. Exchange 2003 Server offers an almost complete implementation of the older MS Outlook GUI interface that features scheduling and utilities. As a result, remote and mobile workers can have complete, secure availability of email even if they don't have a notebook. All mobile users need is an Internet-attached computer with a conventional browser.
  • Unlike Microsoft Exchange 5.5, which has a built-in directory, Microsoft Exchange 2003 Server uses Microsoft Active Directory, representing a more simplified administration and protection model. This makes Exchange Server 2003 simpler to manage and maintain and also allows better protection.
  • Microsoft Exchange 2003 Server has a powerful foundation for seamlessly integrating third-party applications including anti-virus and anti-spamming tools. MS Exchange Server 2003's strong API eliminates the instability often found with Exchange 5.5 Server when integrating third-party utilities.
  • Exchange Server 2003 offers significantly improved scalability and speed in comparison to Exchange Server 5.5. These improvements include more and bigger mailboxes and faster remote access.
  • Microsoft Exchange 2003 Server also has improved searching ability, making it easier and quicker to find vital information when you have to have it.

Benefits Exchange 2003 Server Over an ISP-based or POP3 Email System
If your organization is currently using an email environment hosted by an ISP or if you are running your Microsoft Outlook users in POP3 mode, MS Exchange Server 2003 provides a wealth of improved features covering manageability, responsiveness, capacity, availability, and collaboration:

  • In contrast to the store-and-forward model utilized by POP3 email environments, MS Exchange Server 2003 is based on a central-store model that frees users from dependence on a specific PC or notebook, lowers susceptibility to computer breakdown or viruses, and permits both on-line and off-line email, programmed backup, and advanced sharing and collaboration.
  • Microsoft Exchange Server 2003 offers powerful groupware features that permit work groups to maximize productivity by sharing calendaring, address books, messages, and data.
  • The versatility of Exchange Server 2003 makes it possible to integrate non-Microsoft security enhancements or accommodate wireless devices such as the RIM BlackBerry.
  • Exchange Server 2003 supports advanced administration and tracking utilities to make sure your messaging system is running smoothly.
  • MS Exchange Server 2003 permits complete on-line backup without hurting performance, enabling 24x7 availability by avoiding routine maintenance blackouts.
