Review for LookOut by frytex
Rated 3 out of 5 stars
a solution is to install some program like "winmail.dat opener" or similar. then, in the tools menu tell thunderbird to open the .dat files with this (external) program.
there are a few programs like winmail.dat opener and you can find them in google.
