I have received a pdf file which has been encapsulated in tnef (Transport Neutral Encapsulated Format), a Microsoft format.

Can I open this file to view the pdf using Thunderbird?

Indeed, problem solved with installing KTnef and using its extract function. Thank you for motivating me to find the answer.

Thunderbird doesn't even show standard PDFs. You'll need an external viewer for viewing PDFs. The error message in your screenshot seems to be from the Gnome Document Viewer app, but certainly not from Thunderbird. So you'd need to look for a PDF viewer supporting the Microsoft format.

If this is about a winmail.dat attachment see https://support.mozilla.org/en-US/kb/what-winmaildat-attachment

Thanks christ1, a very good steer! I looked up a tnef viewer, found KTnef in the Ubuntu depository so guess other non MS peeps will find it.

I ran KTnef and immediately tried to open the encapsulated pdf, failed and then tried extracting it (from KTnef) then opened the extracted file and bingo!

Many thanks indeed for your help.
