Use the Microsoft Exchange Server 2007 Setup wizard to install Exchange Server 2007 for the first time on a computer or to add or remove server roles on a computer that has Exchange 2007 installed. If you install Exchange 2007 for the first time, you will use the Introduction page of the Setup wizard. If you want to add or remove server roles, you must either use Add or Remove Programs from Control Panel or use Setup.com from a Command Prompt window. If you use Add or Remove Programs from Control Panel, you will use the Exchange Maintenance Mode page of the Setup wizard.

Before you complete this wizard, be aware of the following:

For e-mail messages to flow correctly, you must install both the Mailbox server role and the Hub Transport server role in each Active Directory directory service site.
For client access to work correctly, you must install a Client Access server in each Active Directory site that has a Mailbox server.
You can install the Mailbox server role, the Hub Transport server role, the Client Access server role, and the Unified Messaging (UM) server role on the same computer or on separate computers.
Confirm that your organization meets the requirements that are listed in Exchange 2007 System Requirements.
To perform the following procedure, you must log on by using a domain account that has the permissions assigned to the Exchange Schema Administrators group, if you have not prepared the Active Directory schema. If you are installing the first Exchange 2007 server in the organization, you must log on by using a domain account that has the permissions assigned to the Enterprise Administrators group. If you have already prepared the schema and are not installing the first Exchange 2007 server in the organization, you must log on by using a domain account that has permissions assigned to the Exchange Organization Administrators group. The account must also be a member of the local Administrators group on that computer.

Note:
When you install Exchange 2007, Setup will create a mailbox for the Administrator user account. When Exchange 2007 creates a mailbox, by default, if an alias is not specified, Exchange 2007 uses the user principal name (UPN) and converts all non-ASCII characters to underscore characters. In some languages that use non-standard character sets, the Administrator user account has by default a non-ASCII value for the UPN. In this case, after you install Exchange 2007, the Administrator account alias will be changed to all underscore characters. To avoid this, confirm that the Administrator account has an ASCII UPN before you install Exchange 2007.

After you have installed Exchange 2007 or added an Exchange 2007 server role, you must open the Exchange Management Console and select the Finalize Deployment tab to finalize your Exchange 2007 deployment. The tasks on this tab apply to features that are enabled by default but require additional configuration. We recommend that you also select the End-to-End Scenario tab to configure end-to-end solutions for Exchange 2007. The tasks on this tab are optional for configuring features.
