Install Microsoft Exchange 2010 the simplest way

The first step would be to install the .NET Framework 3.5.1. 

Click START - ADMINISTRATIVE TOOLS - SERVER MANAGER

Click on FEATURES in the left pane. Click ADD FEATURES in the main pane.

In the window that opens select .NET Framework 3.5.1 Features and follow the wizard.

Depending upon whether you have a installation media for Microsoft Exchange or a copy on one of your drives, navigate to the scripts folder.

Assuming you have an installation media, which is the D:\, open Windows Powershell (run it as administrator) and go to the following location D:\scripts\

You should see the exchange-typical.xml file if you run the 'dir Exchange-t*.*' command

Type the following command:

Add-WindowsFeature NET-Framework,RSAT-ADDS,Web-Server,Web-Basic-Auth,Web-Windows-Auth,Web-Metabase,Web-Net-Ext,Web-Lgcy-Mgmt-Console,WAS-Process-Model,RSAT-Web-Server,Web-ISAPI-Ext,Web-Digest-Auth,Web-Dyn-Compression,NET-HTTP-Activation,RPC-Over-HTTP-Proxy,Web-WMI -Restart

The below command is deprecated. Use it until the server allows.

ServerManagerCmd  -ip exchange-typical.xml

This script will prepare the server for Exchange 2010. Now run the setup.exe file located at D:\

Follow the wizard and change the settings per your requirement.
