Not all files decoded Rated 1 out of 5 stars
The .dat file included a Word Document and a PDF.
Lookout was only able to decode original e-mail text and the PDF. I had to use a stand alone program to fully decode (winmail reader)
Also only works in the window pane, not when the e-mail was opened.
Please consider re-evaluating the LookOut Thunderbird add-on version 1.2.2 and see if there is any improvement.
