5.0, 5.5, and now 2000) is being implemented in organizations that directly
affect the lifeblood of our civilization—the economy, civic rights and politics,
health care, transportation, the arts, and so on. So, let’s move on from this
mantra of Exchange and begin to review the product.
If you are new to Exchange and reading this as your first introduction to
messaging, here is quick summary: In brief, Exchange 2000 is a messaging
architecture that delivers server, client, and networking components with
industry standard application programming interfaces (APIs) and protocols
that provide, retain, and deliver various methods of instant, time-delayed,
and scheduled communication. The Exchange 2000 server components can
store, index, and search personal and publicly shared e-mail messages and
attachments, voice mail messages, telefax messages and attachments, and
almost any form of electronic information. The Exchange 2000 client com-
ponents (Outlook 2000, Outlook Web Access or OWA, and Instant
Messaging or IM), interfaces, and supported protocols allow a wide variety
of methods to utilize these data and messaging services. Exchange 2000
networking components allow the transfer of e-mail between different mes-
saging systems and the synchronization and replication of address book
and directory information within and to similar messaging environments.
These components also allow the scheduling, management, and delivery of
voice, data, and audio conferencing among thousands of participants. The
Exchange 2000 APIs and interfaces enable clients, tools, and third-party
applications to utilize Post Office Protocol v3 (POP3), Simple Mail Transfer
Protocol (SMTP), Messaging Application Program Interface (MAPI), Hypertext
Transfer Protocol (HTTP), and more to access, synchronize, and manipulate
this data. Most of these messaging objects and services are controlled and
integrated in the Windows 2000 network operating system.

This product is best utilized by small organizations. It has all of theimprovements and new features of Exchange 2000, but with just a fewexceptions. For one, Exchange 2000 Server has a limitation of a 16GBinformation store, and it can have only one private and one publicdatabase per server. If you believe your e-mail storage requirements willexceed 16GB on one server, then you need to choose the Exchange 2000Enterprise Server edition. Exchange 2000 Server does not include clus-tering technology, and it does not allow the front-end/back-end configura-tions that allow for more efficient service distribution. These two featuresare not typically required in a small organization, so the product is sizedand priced appropriately for smaller businesses.
