Configuring preferences and options in Outlook.com
I was having the same issue and had made some comments on this thread earlier this year. I tried to get it resolved with support via email but they wanted me to install some third party logging app and then do all kinds of reporting to them. If this was taken seriously by MS they could have had somebody at MS debugging the issue. I am not getting paid to solve their problems for them! I was so frustrated at that point that I went ahead and gave up and got email through GoDaddy for my domain (who by the way uses MS mail). I know that it did get resolved for some of the people who reported it here but it was never fixed for me. I still do not see the option in my outlook.com interface.
