With the introduction of roles that are installed as a command - line switch, the setup and install has
changed considerably from previous editions. However, this considerably reduces the number of extra
services installed on a server. Setup includes new switches to allow for backward compatibility of clients
as well as to give the administrator the ability to perform a higher degree of customization during install.
Scenarios were provided as a tool to help examine how your organization will look when deploying
Exchange Server 2007. Most companies will be performing a migration from a previous edition, and
depending on whether it is a 5.5 or 2003 migration, overall planning, scope, and time frame can
change considerably.
Working with User and
Group Objects
In Exchange Server 2000/2003, Exchange mailbox user objects are created in Active Directory and
thereafter can be viewed in Exchange System Manager. The only operations that can be performed
on these objects from the Exchange System Manager are to purge, reconnect, or run Exchange
tasks. Available tasks performed by the Exchange Tasks Wizard are limited to move mailbox,
delete mailbox, and configure Exchange features. No other Recipient type or group can be
managed in the Exchange System Manager. Moreover, it is difficult to distinguish Recipient types
simply by the object ??™ s icon in Active Directory Users and Computers.
