  • Microsoft Exchange 2003 Server offers superior recovery by adding the capability of eight-node clustering, faster failover, the addition of mount points which eliminate the 24-drive letter limitation, standard storage area network (SAN) connectivity, Volume Shadow Copy Service for backup infrastructure, a Mailbox Recovery tool, and a Restore Storage group.
  • Exchange 2003 Server enhances responsiveness via features such as a /USERVA startup switch for adjusting the allocation of memory address space, public folder replication enhancements, distribution list performance improvements, and suppression of Out of Office notices.
  • Security enhancements offered by MS Exchange 2003 Server include Internet Protocol security support for front-end and back-end clusters, signed Lightweight Directory Access Protocol requests to Active Directory, front- and back-end Kerberos authentication, Internet Information Services 6.0 protection, restriction of distribution lists to validated users, up-to-date Safe and Block data, download filtering, attachment restrictions in Microsoft Office Outlook Web Access (OWA), and public folders access improvements.
  • Microsoft Exchange 2003 Server includes better accommodation of remote and mobile workers by including an Outlook Web Access (OWA) user interface and a broader feature set for Web Outlook, Microsoft Outlook speed enhancements via MAPI compression, HTTP compatibility from Outlook 2003, xHTML and HTML mobile phone browser support, plus synchronization of notifications for Pocket PCs.
  • Management and service are improved by centralizing queues on a per-server basis, improving the user experience, revealing all system queues, controlling cookie permission, utilizing Exchange System Manager to move log files, including a multiple-client Move Mailbox function, and providing dynamic distribution lists, public folder Send hierarchy, and public folder affinity to control referrals.

Advantages of MS Exchange 2003 Vs. MS Exchange 5.5 Server
Microsoft Exchange Server 2003 delivered significant enhancements in functionality over Microsoft Exchange Server 5.5 in important areas including accessibility, manageability, security, stability, scalability, and performance.

  • MS Exchange Server 2003 brings a dramatic increase in capability compared to the Exchange 5.5 web client. Microsoft Exchange Server 2003 provides an almost complete implementation of the traditional Microsoft Outlook interface that features calendaring and utilities. Because of this, mobile workers can have complete, secure availability of email even if they don't have a notebook. All they require is a web-connected computer with a conventional web browser.
  • Unlike MS Exchange 5.5 Server, which incorporates its own directory, Microsoft Exchange 2003 Server uses Active Directory, representing a more streamlined administration and protection model. This makes MS Exchange Server 2003 easier to manage and support and in addition allows better security.
  • MS Exchange 2003 Server has a strong architecture for transparently integrating non-Microsoft utilities such as anti-virus and anti-spamming software. MS Exchange 2003 Server's strong Application Programming Interface (API) eliminates the instability often found with Exchange 5.5 when integrating third-party utilities.
  • Microsoft Exchange Server 2003 offers greatly improved capacity and performance in comparison to Microsoft Exchange Server 5.5. Improvements allow more and larger mailboxes and speedier remote access.
  • Microsoft Exchange 2003 Server also provides improved searching ability, making it simpler and faster to find important data when you have to have it.

Advantages Microsoft Exchange Server 2003 Compared to an ISP-provided or POP3 Email System
If your business is now using an email system hosted by an Internet Service Provider or if you are running your Outlook users in POP3 mode, MS Exchange 2003 Server offers an array of improved features covering manageability, performance, size, availability, and collaboration:

  • In contrast to the store-and-forward model utilized by POP3 email systems, Exchange Server 2003 is based on a central-store architecture that frees users from dependence on a specific personal computer or laptop, lowers vulnerability to computer failure or viruses, and allows both on-line and off-line email, programmed backup, and advanced groupware.
  • Exchange Server 2003 has powerful groupware features that allow work groups to improve efficiency by sharing calendaring, address groups, correspondence, and data.
  • The flexibility of Microsoft Exchange 2003 Server allows you to integrate third-party security add-ins or accommodate wireless computers such as the RIM BlackBerry.
  • Microsoft Exchange 2003 Server works with advanced management and monitoring utilities to confirm that your messaging system is running efficiently.
  • MS Exchange Server 2003 permits complete on-line backup without hurting productivity, supporting 24x7 operation by avoiding routine downtime.
