How we tested Exchange 2003 and Outlook 2003.We installed our Exchange 2003 Server on an HP Compaq ProLiant DL360 G3 server, with twin 2.4-GHz Intel Xeon processors, 1G byte of RAM and a 36G-byte RAID5 array, running Windows Server 2003. A second, identically configured DL360 was used as the proxy server for the HTTP\/RPC tunneling testing. We created a new Active Directory tree to hold our new Exchange 2003 Server.Outlook 2003 was installed on several Windows XP Professional workstations of various makes and models. We mainly used Internet Explorer 6.0, but also tried older versions to test the basic modes of OWA.We put Exchange 2003 through its paces by performing day-to-day groupware functions, such as appointment and task management, as well as sending a plethora of e-mail. We also had fun seeing what would trip the "junk e-mail" filters. Back to review: "Favorable returns on Exchange"
