Windows Live Hotmail
Date of use:2004-2012
Hotmail used to be great but not any more. I have more then one account for work, personal and misc reasons. But I have all of them blocked and been locked of my email for sending too many emails. When you have four email accounts and all are blocked and they never tell you why. And customer service is a joke. I used to love Hotmail but now it just is a major pain.
