Original Title: Windows Live Mail - cannot send mail

Windows Live Mail has been working correctly regarding the sending of emails in the past, but recently I cannot send through Windows Live Mail.  If I go to my gmail account I can send mail and it show up as sent mail in my Windows Live Mail.    The error I get is: An unknown error has occurred.

Subject 'Re: Marking of AED units'
Server: 'smtp.gmail.com'
Windows Live Mail Error ID: 0x800CCC0B
Protocol: SMTP
Port: 465
Secure(SSL): Yes

The Tasks message is:

a red  X  shows with the message:  send 5 message(s) using Gmail (garyfhuber)     with a status of Failed.

I do not know if this next part pertains to this, but when deleting mail from my Windows Live Mail an error will occur if I delete to fast.  

the error message is:  The server has rejected your login.  Please verify that your user name and password are correct.  This error will not happen if I delete slowly.
