I have installed Windows Live Mail on a new Windows 10 system.  Receiving mail with it is fine, but when I try to send a message I get an error: Socket error 11001; Error ID 0x800ccc0d (The host could not be found).  I have verified the account settings with my ISP (ATT) and they are all correct.  Have also tried uninstalling and reinstalling Windows Live Essentials, disabling the firewall temporarily, and a couple of other things, but nothing has worked.  I have an older computer with WLM running Windows 10, and that works fine.  Any suggestions?
