Starting on August 15 I was unable to send emails using Windows Live Mail ( Version 2011 (Build 15.4.3555.0308).  I can receive emails and the emails to be sent are in the "Sent Items" folder.  I can send and receive when using the mail server on the web.  When I went to another WiFi location I could send and receive emails using Windows Live email.  Sometimes when I try to send I get a message from Windows Live Mail "The spell check on this document was halted. Do you want to send anyway".  I have tried changing the  Outgoing mail smtp from 25 to 587 with no effect. This problem occurs on two separate laptops.  I have spoken to my ISP provider who says it is not there problem.
