I want to print a thunderbird email folder with attachement in one pdf (or several, and then merge them).
With PDF printer, we can print all the mails of a thunderbird folder, but without attachements. And the problem is that you have to confirme for each mail the nam under which it will be registered. It is a problem when you have thousands of mails besides that this name is based on the subject of the message, and therefore that there are often duplicates ... !
It is just unusable !
Though there are specialized tools to do this, PDF tools don't have these feature.
Specialized tools are expensive: https://www.bitrecover.com/mbox-converter/thunderbird/
It is a lack that must be filled: it is hard to pay for your solution that is supposed to be very complete, and have to use other one to answer this need.
These tools are very useful for archives or when in a trial you have to produce all your mails....
The problem is the same with Outlook: though it is possible to print in only one pdf, attaachement are printed separately instead of being printed just after the mail.
Hope you will add these functunalities soon !
