Advantages of Exchange 2003 Over MS Exchange Server 2000
MS Exchange 2003 Server offers enhancements in capability over Exchange Server 2K in key areas such as disaster recovery, throughput, security, mobility, collaboration, and simplicity of management.

  • MS Exchange 2003 Server offers superior disaster recovery by including the capability of 8-node clustering, faster cluster failover, support for mount points which overcome the 24-drive letter limit, SAN compatibility, Volume Shadow Copy Service for backup infrastructure, a Mailbox Recovery tool, and a Restore Storage group.
  • Exchange 2003 Server enhances responsiveness through innovations such as /3GB and /USERVA startup switches for tuning the allocation of memory and memory address space, public folder store replication improvements, distribution list caching improvements, and control of Out of Office notices.
  • Security improvements introduced by Exchange 2003 Server 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 security, restriction of distribution lists to authenticated users, real-time Safe and Block lists, download filtering, attachment blocking in Microsoft Office Outlook Web Access (OWA), and public folders access enhancements.
  • Microsoft Exchange 2003 Server includes better accommodation of remote and mobile workers by including an Outlook Web Access (OWA) user interface and a more extensive feature set for Web Outlook client, Microsoft Outlook speed enhancements via MAPI compression, HTTP access from Outlook, cHTML aND.htmL mobile phone browser capability, and synchronization of notifications for Pocket PCs.
  • Manageability and serviceability are improved by centralizing queues on a per-server basis, enhancing the user interface (UI), exposing all system queues, enabling cookie authorization, utilizing Microsoft Exchange System Manager to move log files and queue data, including a multi-user Move Mailbox function, and adding dynamic distribution lists, public folder Search capabilities, and public folder affinity to manage referrals.

Improvements of MS Exchange Server 2003 Compared to MS Exchange 5.5
MS Exchange Server 2003 offered major enhancements in functionality over Exchange 5.5 Server in key areas affecting accessibility, ease of management, protection, stability, scalability, and performance.

  • Exchange 2003 Server offers a significant increase in functionality over the Microsoft Exchange 5.5 web client. MS Exchange Server 2003 offers a nearly identical version of the older MS Outlook interface that features calendaring and tools. Because of this, remote and mobile workers can have full, protected availability of email even without a laptop. All they need is an Internet-connected PC with a standard web browser.
  • Unlike Exchange Server 5.5, which uses its own directory, MS Exchange 2003 Server takes advantage of Microsoft Active Directory, providing a more simplified administration and protection structure. This makes Exchange Server 2003 less expensive to manage and support and in addition offers better protection.
  • Exchange Server 2003 has a strong architecture for transparently integrating non-Microsoft utilities such as virus and spam scanning tools. Exchange 2003 Server's versatile API eliminates the technical risk associated with MS Exchange Server 5.5 when integrating independent utilities.
  • MS Exchange 2003 Server delivers significantly increased scalability and speed in comparison to MS Exchange 5.5 Server. Improvements include more and bigger mailboxes and speedier offsite connectivity.
  • Microsoft Exchange 2003 Server also offers improved search ability, making it easier and quicker to find important data when you need it.

Benefits Microsoft Exchange Server 2003 Vs. an ISP-based or POP3 Email System
If your organization is currently running an email system hosted by an Internet Service Provider (ISP) or if you are operating your Outlook users in POP3 mode, MS Exchange 2003 Server provides a wealth of improved features in the areas of ease of management, responsiveness, size, reliability, and group support:

  • Unlike the store-and-forward technique utilized by POP3 email environments, Microsoft Exchange Server 2003 uses a central-store model that liberates users from reliance on a specific PC or notebook, reduces susceptibility to hardware breakdown or viruses, and permits both on-line and off-line email, automatic backup, and sophisticated collaboration.
  • Microsoft Exchange Server 2003 has an array of groupware features that allow teams to maximize productivity by sharing calendaring, address books, messages, and files.
  • The flexibility of Exchange Server 2003 makes it possible to install non-Microsoft security enhancements or accommodate wireless devices such as the BlackBerry smartphone.
  • MS Exchange 2003 Server works with powerful administration and monitoring utilities to make sure your messaging system is running efficiently.
  • MS Exchange 2003 Server permits complete on-line archiving without disrupting performance, enabling 24x7 operation by eliminating routine downtime.
