O.k., it's decodes the winmail.dat. After that I got a rtf-attachment which contains the email text and an attachment in binary format (Untitled Attachment) which contains the addressboook entry. But this attachment is not the original vcf card. Of course I can extract the entries manually out of this file by using a hex or text editor and paste it in a new addressbook entry, but this is not a good workflow.
I really appreciate your work and I think it is just a small fix necessary to get a working vcf. How can I help you on this topic? Send you a sample mail? I use TB 52.4.0 (64bit) on Ubuntu.

This review is for a previous version of the add-on (1.2.19).
