A couple days ago Windows Live mail suddenly stopped sending my emails, they are in the outbox.  I can receive emails but not send. I get the error:

The connection to the server has failed.

Subject 'test'
Server: 'mail.mchsi.com'
Windows Live Mail Error ID: 0x800CCC0E
Protocol: SMTP
Port: 25
Secure(SSL): No
Socket Error: 10060

Nothing has changed in the settings and I can send my emails when going online directly to my email provider (Medicom). but no longer through Windows Live Mail.

When I contacted Microsoft support I was told that Windows Live Mail is obsolete and no longer supported???

Under the Advance tab :

My outgoing email is SMTP  port 25

Incoming is POP3 110

the "server requires a secure connection" is not checked.

thanks for any assiatance
