I've only had Widows & (and Live Mail) less than two months and read interest the way Microsoft is ignoring this issue. Notice the link
http://windowslivehelp.com/thread.aspx?threadid=6d0fd8d8-774c-421e-aa8b-90ad6074c2bc which has been locked since Jan 26 2011 because this was a known issue.
Have any of the users found an alternative email client yet?
