Organizing and accessing contact information in Outlook.com
No, its not resolved. Its the problem of Facebook and not Microsoft in general. Just try to use any other 3rd party chat tool for FB Chat (IM+ / Trillian) or whatever is your preference. You'll face the same trouble.
Just for your update, I've sent at least 20 mails to FaceBook over the same issue but haven't got any reply. I guess we should team up there on Facebook to get issue resolved. Let me know about your thoughts.
Thanks and Regards,
