I'm using Live Mail 2011 and my PC is set up so that I don't need to sign in with a password. The program checks for & downloads emails automatically. Last week, I was suddenly prompted for a password, but despite using the correct password for my email account, I remain locked out and can only see my emails through the email server. What's wrong with my Live Mail account and how to fix it?
