554 error in Live Mail

Earlier error included:

An unknown error has occurred.

 Server Error: 554 Server Response: 554 fed1rmimpo306 cox rejected for too many login failures

Server: 'smtp.cox.net' Windows Live Mail Error ID: 0x800CCC6F Protocol: SMTP Port: 465 Secure(SSL): Yes

This error occurs when your connection has been blocked for sending too many bad SMTP email commands which is often an indication of an email trojan infection.  Other possible causes could be an email client on any PC or device which connects to your home Internet which is experiencing problems too.  Many times there is an Apple device which is experiencing problems.  If you have any iPhones or iPads you could try removing and re-adding your email settings.  It'll take a few hours from once the problem is resolved for the block to be removed.

Thanks Chris, I'll give it a try! Hopefully this will work.

This has happened to me before too.  Someone at work got us all locked out by having a bad passcode on their phone.
