Seems it does nothing.
What should it do? How does this work?
The description is not saying how to use it.
As stated in the description this add-on decodes winmail.dat Transport Neutral Encapsulation Format or TNEF attachments. TNEF is a proprietary email attachment format used by Microsoft Outlook and Microsoft Exchange Server.
In order to use this add-on you simply open an email with a winmail.dat file attached and it will automatically attempt to decode it. No user interaction is required.
