I received this issue last week, so I removed the Outlook.com hosted email address *** Email address is removed for privacy *** from Live Mail. It worked until today, when again I got this same error.

I don't want to keep removing and installing this email account to get it working. Please fix it.

Other details:

My Live Mail client has 5 other outlook accounts - those are unaffected. For *** Email address is removed for privacy *** I have it also installed on the same computer in Outlook 2013 (software), and it in unaffected. Note, I do not use Outlook 2013 because it sucks, I use Live Mail only, I just want to point out all these details so you know it's not my firewall or anything - as if it were, the other accounts in Live Mail would stop working as well.

Everyone on the Status page for the accounts says it is operating fine.
