Benefits of Updating from Microsoft Exchange 5.5 Server Exchange Server 2003 offers major improvements in functionality over Exchange 5.5 Server in key areas including accessibility, manageability, security, stability, capacity, and performance. The 2003 version of MS-Exchange brings a dramatic increase in functionality over the Microsoft Exchange 5.5 web client.

This means that mobile workers can have full, secure access to email even without a notebook. All they need is an Internet-connected computer with a standard web browser. Unlike Microsoft Exchange 5.5, which has its own directory, Microsoft Exchange Server 2003 uses Active Directory, providing a greatly simplified administration and security model. This makes Exchange Server 2003 easier to manage and support and also offers tighter security. Exchange Server 2003 has a strong foundation for seamlessly integrating third-party applications such as virus scanning packages and anti-spamming tools. Exchange Server 2003's strong Application Programming Interface (API) eliminates the instability associated with Exchange 5.5 when adding third-party utilities. Microsoft Exchange Server 2003 offers significantly improved capacity and performance over Exchange 5.5. This means that you can have more and bigger mailboxes and faster remote access. Upgrading to Microsoft Exchange Server 2003 also brings better searching ability, making it easier to retrieve vital information when you need it.

An advanced managed, remote accessible application programming interface (API) enhances collaborative development. Manageability and serviceability are improved by centralizing queues on a per-server basis, improving the User Interface, exposing all system queues, enabling cookie authorization, using 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, public folder Search capabilities, public folder Send Contents, and public folder affinity to control referrals. Benefits of Migration from an ISP-based or POP3 Email System If your small business is currently using an email system hosted by an ISP or if you are running your Outlook clients in POP3 mode, Microsoft Exchange 2003 Server offers an array of improved features in the areas of manageability, performance, capacity, availability, and collaboration: Unlike the store-and-forward model used by POP3 email systems, Microsoft Exchange Server 2003 Server uses a central-store model that frees users from dependence on a specific desktop or notebook computer, reduces vulnerability to hardware failure or virus attacks, and allows both on-line and off-line email, automatic backup, and sophisticated sharing and collaboration. Exchange Server 2003 has powerful collaboration features that allow work groups to increase productivity by sharing calendaring, address books, messages and files. The flexibility of Exchange Server 2003 makes it possible to add third-party security enhancements or accommodate wireless devices such as the RIM Blackberry wireless handheld.
