Outlook vs. Outlook Express

Despite their similar names and the fact that they’re both made by Microsoft, “Outlook” and “Outlook Express” are completely different programs. Outlook has an orange icon; Outlook Express has a white-and-blue icon. We only use Outlook. Do not under any circumstances run Outlook Express. Doing so will make configuration changes to your email account that will make it impossible for you to access e-mail, contacts, calendar, public folders, and the Global Address List. We recommend deleting any Outlook Express icons that you might have in your Start Menu to ensure that you don’t accidentally run Outlook Express. To do so, simply right-click on an Outlook Express icon and select “Delete”.
