When I try to send messages from Windows Live Mail it stalls. When I click send/receive all I see is a long green line in the send window as it tries to send. The message says "Having problems connecting to outgoing server"

I have repaired Windows Essentials but that does not help. When I reboot, I can get into my WLM momentarily to check messages and can even send one. After than, it stalls again and I can not send any. Maybe I need to set up the account again?  Reconfigure something? Not sure how to do it.
