This Connection is Untrusted for Outlook mail
I get this error message anytime when I try log in on mail.live.com using my email firstname.lastname@example.org but when I use secondary account email address I can log in without any errors. Nothing has change exempt my email addresses. I have tried all other fixes which have been posted to fix this problem. When I look into more about the error, I notice Firefox was trying to log in to my yahoo mail account, which is mail.yahoo.com. Why is Firefox trying to log in on yahoo when I typed in live.com URL.
This just started couple weeks ago, up until then I could log in to my live.com account. No virus or malware or time wrong. I get the like error message with IE and Chrome. Where is problem and how to fix??
