Managing personal Outlook.com account settings, security, and privacy
I have been trying to fix this too and finally accomplished it. You go up to the right hand side and click on the icon that looks like a wheel. On the bottom of what comes up is the word help. click on that then find the sentence about log in and password problems. Then when it offers you to reset your password do just that. Once I changed mine I no longer had my e-mail pop up on my work computer so that everyone could read my e-mails without putting in my log in information. Yea!!! Hope this works for you.
