Configuring preferences and options in Outlook.com
I just found a setting i never saw before. Made some changes and let's hope it works for me. If you guys wanna try, follow this address "account dot microsoft dot com " and click on "Your Info" tab and then "Profile" tab. I found the wrong language set there, so hopefully it cascades down to whatever database they track language of communication. You may have to change the language to a wrong one, then the one you want. Example: if you want language A, but profile shows language C, set language to language B, save and lastly set language to language A and save.
