How to Change a Username in Outlook Expressby Ian Moore
Outlook Express is an email client, a business planner and a host of other things. Instead of having to log into your webmail server, email can be accessed by simply logging onto your Outlook Express account. If you have recently changed email addresses or just want to change your user name, it's an easy operation.
How to Change a Username in Outlook Express
Open Outlook Express. Go to "Tools" on the top toolbar menu. Click "Account Settings."
Highlight your user name in the list provided and click the icon that says "Change." This icon has an image of a hand and paper.
Go to "User Name," directly under "Log-On Information." Highlight your current user name with your cursor and delete it.
Enter your new desired user name. Click "Next" and then "Finish" to save your settings.
