Hello, my spouse just began using a computer with Windows 7. She now has Outlook.com for her email account. Can she add her previous Outlook Express address to Outlook and see mail addressed to either account in Outlook? Thanks very much.
You don’t say which e-mail service your wife is using, but there are a couple of ways she can see e-mail from that account in her Outlook.com inbox. If that account has an e-mail forwarding features, you can forward the mail to the Outlook.com account. The process will vary depending on where she has her old e-mail address and not every service offers this.
Or you can use Outlook’s e-mail fetching service. I detailed how to do this in this article. How Do I add Old E-mail Address To My Outlook.com? 
Hopefully this shouldn’t be a difficult process at all.
