Perfect! But might require to be compatible with "Thunderbird Conversations" addon. Puntuado con 4 de 5 estrellas
Works fine with TB 38.3.0 under Windows 10!
For those who might still have problems with winmail.dat, LookOut is not compatible with the addon "Thunderbird Conversations". The solution is to open the mail in a new tab (right-clic on the email). This way, Thunderbird uses the old template to display the message and winmail.dat is decomposed. Attachments can now be open... Again, thank you Micro$oft for your great work! :-(
