The first step is to create the accounts for Outlook Express that are available in Outlook. In Outlook go to the Tools/Accounts item and export all desired email accounts to their respective IAF files making certain to note the folder these files are written into.

The second step is open Outlook Express, go to the Tools/Accounts menu item and import those IAF files to create the accounts for OE. This will essentially deploy Outlook Express as a functional email client.

The last step is to set Outlook Express as the default email client in Internet Explorer (or whichever browser is being used). In IE go to the the Tools/Options menu item, then to the "Programs" tab and select Outlook Express as the default email program and select OK.
