You can set up multiple Outlook Express user accounts if several people share the same computer and each person needs their own account. Once you set up multiple accounts, each user can gain access to the Internet and receive e-mail messages without logging off the computer and logging back on with a different user profile.
After you set up multiple accounts, you can specify which is used when you start Outlook Express. You can choose to be prompted for an account every time you start Outlook Express, to automatically use the same account every time, or to use the Windows logon account.
If working hours overlap for more than one person on the same computer, you should choose to be prompted for an account every time you start Outlook Express. If you rarely share the computer, you should use the same account every time you start Outlook Express. If each person uses only the computer that he or she is logged on to, you should set up Outlook Express to use the Windows log on account.
