If anyone needs to Import from Windows Live Mail to Thunderbird. I'd like to share my experience with eSoftTools Window Live Mail Converter to convert WLM to Thunderbird, it is the best software because it exports my WLM files in few steps, and also offers to convert Windows Live Mail to multiple files to PST, EMLX, MSG, MBOX, HTML, Office 365 and other file formats. It also provides free demo versions that can convert the first 25 emails from WLM to Outlook pst.
