Hello,

I'm currently unable to send Gmail messages using Windows Live Mail (WLM) 2012. I am receiving Gmail messages on WLM. All of the other accounts I have on WLM will send/receive email messages, but not my Gmail. 

This morning, I sent a message from my Gmail account using WLM and got the following error message: 

An unknown error has occurred.
Subject 'Subject Line of Email'
Server: 'smtp.gmail.com'
Windows Live Mail Error ID: 0x800CCC0B
Protocol: SMTP
Port: 465
Secure(SSL): Yes

The message is not in my sent items or drafts folder. It seems to have disappeared and was never sent. I am able to send web based Gmail messages. Please advise. Thank you in advance for your help.
