After the automatic MS updates today, my Live Mail is stuck in the Off Line mode with the following error:

Unable to send or receive messages for the <Company> (my login) account. Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity.

Server: 'my mail server'
Windows Live Mail Error ID: 0x800CCC0F
Protocol: POP3
Port: 110
Secure(SSL): No
Socket Error: 10053

I'm using Windows 7 Ultimate and IE 11. [There is no "Off Line" toggle in IE 11.)]

How can I fix this?
