Those with an Outlook Express email account can sign into the Outlook Web app to check their email. Since Outlook Express is no longer supported by Microsoft, users must sign up for Outlook.com.
To sign up for Outlook.com with an existing Outlook Express account, users must go to the sign up page. They can then enter the email addresses and passwords to the Microsoft accounts used to access their Outlook Express emails. Once the user clicks "Get Started," Outlook will run the Mail Migration program. This will automatically move all contacts to the new email account. From there, users can sign into Outlook.com using their Outlook Express credentials.
