Overview of Exchange Server 2003
Exchange 2003 Server provides a dependable, scalable, and easy-to-manage platform with round-the-clock email and team support as well as affordability. MS Exchange 2003 Server supports a broad range of team functions, including group scheduling abilities, discussion areas, and team folders, and also makes available information that extends over territorial, logical, and architectural divisions with features that include Instant Messaging, real-time information, and video conferencing. Exchange Server 2003 delivered improvements over MS Exchange 2000 Server in important areas that cover security, performance, and remote access.

Microsoft has terminated support for Microsoft Exchange Server 2003, making information technology managers deal with all the problems involved in supporting an end-of-life messaging platform. Despite this, a large number of Exchange sites are still running Microsoft Exchange 2003. Progent's Microsoft-certified network consultants offer in-depth backgrounds maintaining Microsoft Exchange 2003 and can help your company to administer and repair your current Microsoft Exchange 2003 solution or help you to design and execute an economical upgrade to an up-to-date version of Microsoft Exchange. (Refer to Progent's Exchange 2016 migration support services and Exchange 2013 expertise.)

Improvements of MS Exchange Server 2003 Compared to Exchange Server 2K
Exchange 2003 Server offers enhancements in capability over Exchange 2K Server in key areas such as recovery, throughput, protection, mobile access, teamwork, and manageability.

  • Exchange Server 2003 delivers enhanced recovery by adding the capability of 8-node clustering, faster cluster failover, support for mount points which eliminate the 24-drive designation limitation, standard storage area network (SAN) connectivity, Volume Shadow Copy Service for database backup, a Mailbox Recovery Center utility, and a Restore Storage group.
  • MS Exchange Server 2003 improves responsiveness via innovations such as /3GB and /USERVA startup switches for tuning the use of memory and memory address space, public folder replication enhancements, distribution list caching enhancements, and suppression of Out of Office messages.
  • Security improvements offered by Exchange Server 2003 include Internet Protocol security support for front- and back-end clusters, signed Lightweight Directory Access Protocol (LDAP) requests to Active Directory, front-end and back-end Kerberos validation, IIS 6.0 protection, limiting of distribution lists to authenticated users, real-time Safe and Block data, inbound recipient filtering, attachment restrictions in Outlook Web Access, and public folders permissions enhancements.
  • Microsoft Exchange 2003 Server includes improved accommodation of mobile users by including an Outlook Web Access (OWA) user interface and a more extensive feature set for Web Outlook, Microsoft Outlook performance improvements via MAPI compression, HTTP compatibility from Microsoft Outlook, cHTML aND.htmL mobile phone browser support, plus synchronization of notifications for handheld computers.
  • Manageability and service are improved by organizing queues on a per-server basis, improving the user interface (UI), revealing 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 Send hierarchy, and public folder affinity to manage referrals.

Improvements of Microsoft Exchange Server 2003 Vs. MS Exchange 5.5 Server
Exchange 2003 Server offered significant improvements in capability over MS Exchange 5.5 in key areas including access, manageability, security, reliability, capacity, and speed.

  • Microsoft Exchange Server 2003 offers a dramatic improvement in capability compared to the MS Exchange 5.5 web client. Exchange 2003 Server provides a nearly identical version of the older MS Outlook GUI interface that features scheduling and tools. As a result, remote and mobile users can have complete, secure availability of email even if they don't have a notebook. All they need is an Internet-connected PC with a conventional browser.
  • In contrast to Exchange Server 5.5, which uses a built-in directory, MS Exchange Server 2003 utilizes Active Directory (AD), representing a more streamlined management and protection structure. This makes Microsoft Exchange 2003 Server simpler to manage and support and also allows better security.
  • Microsoft Exchange 2003 Server has a strong architecture for transparently adding non-Microsoft utilities such as virus and spam scanning tools. MS Exchange 2003 Server's strong API does away with the instability often found with MS Exchange Server 5.5 when adding third-party utilities.
  • Microsoft Exchange Server 2003 offers greatly increased capacity and speed in comparison to Exchange 5.5 Server. These improvements allow more and bigger mailboxes and faster remote access.
  • MS Exchange Server 2003 also has better search ability, making it simpler and quicker to retrieve vital information when you have to have it.

Advantages MS Exchange 2003 Server Vs. an ISP-based or POP3 Email Environment
If your organization is currently running an email environment hosted by an Internet Service Provider or if you are running your Outlook clients in POP3 mode, MS Exchange Server 2003 offers an array of improved features in the areas of ease of management, responsiveness, size, reliability, and collaboration:

  • In contrast to the store-and-forward model used by POP3 email systems, MS Exchange 2003 Server is based on a central-store architecture that liberates users from dependence on a specific personal computer or notebook, lowers susceptibility to computer breakdown or viruses, and permits both on-line and off-line operation, automatic backup, and advanced sharing and collaboration.
  • Exchange 2003 Server has powerful collaboration features that permit teams to improve productivity by sharing scheduling, address groups, messages, and data.
  • The versatility of MS Exchange Server 2003 allows you to integrate non-Microsoft security add-ins or support wireless devices such as the BlackBerry smartphone.
  • Exchange Server 2003 supports advanced management and monitoring tools to confirm that your messaging system is operating efficiently.
  • Microsoft Exchange Server 2003 allows complete on-line archiving without hurting productivity, supporting round-the-clock operation by avoiding scheduled maintenance blackouts.
