Topic Objective

set of features and components to support the development of collaborative
solutions.
Exchange 2000 is the first product to take advantage of a new data storage
technology called the Web Storage System. Exchange 2000 uses the Web
Storage System to store all of its data. An understanding of the data structure of
Exchange 2000 will enable you to perceive how the Web Storage System
integrates with Exchange 2000.
Topic Objective
To list the topics related to
introduction to
Exchange 2000.
Lead-in
Exchange 2000 is a
messaging environment that
supports the development of
collaborative solutions.

Front-end and back-end deployment
Exchange 2000 can be configured as a set of front-end and back-end
servers, enabling users to connect to virtual Internet Protocol (IP)–
addressable front-end servers, while storing messages and collaboration data
on separate back-end servers. This configuration flexibility provides new
opportunities for enterprise customers to tailor their system architecture to
meet the demands of corporate acquisition and growth.
!
Clustering
Clustering allows you to group servers that host the same set of services into
manageable units to improve the reliability of the services. If one server in
the cluster fails, another server in the cluster can start and keep the services
running. Clustering support in Exchange 2000 has been enhanced to feature
Active/Active clustering. Based on the Microsoft Clustering Services of
Microsoft Windows
®
2000 Advanced Server, Active/Active clustering
enables all of the servers used in a cluster to actively process messaging
requests and distribute the load evenly between the servers in the cluster,
thereby increasing scalability.

Presentations
Company Meeting.aviExchange 2000 stores its data in databases. Exchange 2000 databases are more
commonly referred to as stores. Exchange 2000 can store all kinds of data such
as e-mail messages, graphics, voice mail, and video presentations.
Exchange 2000 supports multiple stores within one logical database. All store
data is kept in Joint Engine Technology (JET) databases.
Store Types
There are two kinds of stores in Exchange 2000, mailbox stores and public
stores. These replace the private and public information stores of earlier
versions of Exchange. Each store is referred to as a Web Storage System.
During the installation process, Exchange 2000 creates a default mailbox store
and a public store.
!
Mailbox store. A database that contains folders and items intended for use
by a single user or program. A mailbox is the delivery location for all
incoming messages for a designated owner. Only the owner of a mailbox
can access the contents.
A mailbox can contain received messages, message attachments, folders,
documents, and other files. Information in a user's mailbox is stored in a
mailbox store on an Exchange 2000 server. Exchange 2000 can have
multiple mailbox stores. However, mailbox stores cannot be replicated to
other servers running Exchange 2000.

8 Module 1: Introduction to Exchange 2000 and the Web Storage System Folder Trees
!
Public Folder Trees
$
Provide access to the default public and mailbox stores
$
Support HTTP, SMTP, POP3, IMAP4, NNTP, and MAPI
!
Advantages of Public Folder Trees
$
Provide a common place for data storage and application hosting
$
Configure permissions for data and applications at folder level
$
Easy to enhance or adapt the folder for another purpose
!
Folder Tree Replicas
$
Distribute the user load on servers
$
Distribute public folders across geographical areas
$
Back up public folder dataIn each store are folder trees that contain Exchange 2000 items, such as e-mail
messages, documents, and other folders. A folder tree is a hierarchy of folders


Topic Objective
To define public folder trees
and their advantages, and to
describe the features of
replicas.
Lead-in
Folders provide access to
data in public stores and
mailbox stores. For a
developer, public folders are
significant components of a
Web solution.
Key Points
Emphasize the distinction
between a MAPI folder
hierarchy and all other folder
hierarchies. In other
hierarchies MAPI can
access only the mailbox
folder and the public folder
tree, if you create a new
folder tree, everything can
access it except MAPI.
Module 1: Introduction to Exchange 2000 and the Web Storage System 9 Folder Tree Replicas
You can configure a folder tree to have replicas on multiple servers. Replicas
are useful for distributing the user load on servers, distributing public folders

!
Easier access to directory information.
Lightweight Directory Access Protocol (LDAP) is the preferred access
protocol for directory information.
!
Active Directory Connector.
The Active Directory Connector synchronizes directory information from a
previous Exchange System directory to Windows 2000 Active Directory.

Topic Objective
To list the benefits of
integrating Active Directory
with Exchange 2000.
Lead-in
In Exchange 2000, Active
Directory stores all
Exchange 2000 directory
information.

http://servername/public/Survey/SuzanFine.xlsAlthough you store items in Exchange 2000 databases, you use the Web
Storage System technology to access the items. The Web Storage System is a
database organized into a hierarchy of folders.
Web Storage System Resources
Each folder in the Web Storage System can contain any number of items, called
resources. A resource can be any Exchange item, such as an e-mail message, an

relational database, such as Microsoft SQL Server
™
. For example, you can
perform a search on all expense report resources that have the custom property
total set to a value of over $500.00.
You can also extend the default schema for use in your programs. For example,
you can create the schema definition for an expense report and associate default
schema properties of the Web Storage System and custom properties with the
definition.

Content Indexing and Searching SupportEach store in Exchange 2000 is a Web Storage System database. The Web
Storage System database offers flexibility for developing programs.
Multiple Database Support
You can define multiple stores with Exchange 2000. Because stores have no
size limit, you can use multiple stores placed on different servers to enhance the
flexibility of backup and restore tasks, indexing, and replication. In addition,
you can configure nearly every store control on a store-by-store basis.
