It doesn’t take a lot for Microsoft Outlook 2003 to run. All you need is a computer that has a speed of at least 233 MHz, with 128 Mb of RAM, and at least 400 Mb of available hard drive space. You also need basic computer components, such as a monitor, mouse, keyboard, and CD or DVD ROM drive. Last but not least, Windows 2000 with Service Pack 4 or Windows XP must be installed on the computer.
