  1. Save the whole e-mail message to an *.EML file via File, Save As, or Drag-and-drop.
  2. Open the *.EML file in a text editor such as Wordpad or Notepad.
  3. Locate the line Content-Type: application/ms-tnef;, and change the Content subtype to something else, such as Content-Type: application/zzz;
  4. Locate the line name='winmail.dat' and change to name='winmail.tnf'. You may change the winmail part as well, if desired.
  5. Save the *.EML file from the text editor.
  6. Double click the *.EML file from the Windows File Explorer. This will open the message in a mail window and the TNEF attachment should now be available for saving.
  7. Drag the saved attachment into the Winmail Opener program. Decoded attachments will then be there and can be dragged or opened.
