It sounds like there are solutions to convert windows live mail to everything up to outlook 2013 (32 bit) but then after that, no answers. I bought a program called Kernel which claimed to be able to make the conversion, but it did not work. In fact, it could not even find the proper files when asked to search. Under "Storage Folders", in Live Mail),  I have about 30 folders per year, going back to 2006. Although you can see all of the folders when you open Live Mail, you can only see 5 files in the 2015 folder. It is similar for the other years, you just see about 4 or 5 files when you search, and there are you see 30 files when you open Live Mail. Bottom line is that you can't transfer what you can't see, or find.
