Since having been forced to use SKYPE, instead of MSN MESSENGER, I've found I no longer get notification of new email.. Have tried as suggested, signing into  my Microsoft account pressing ALT+F  hovering over options, then clicking on the sound for incoming e-mails but it don't work....Not pleased at all that this has been taken away..Also find the the OUTLOOK is so basic, there is no spell checker, have tried to change back to HOTMAIL, couldn't find the "revert back" as was advised would get the choice to do..

      regards, Pam

P.S.   I'M AMAZED AND DISAPOINTED THAT NOBODY SEEMS TO HAVE AN ANSWER TO THIS.
