I am surprised that this works. ox-koma-letter does the following: #+begin_src elisp (unless (assoc "default-koma-letter" org-latex-classes) (add-to-list 'org-latex-classes '("default-koma-letter" "\\documentclass[11pt]{scrlttr2}"))) #+end_src and so you should be using default-koma-letter here. Unless, of course, you have defined your own scrlttr2 org LaTeX class somewhere (although you say you have not)? -- : Eric S Fraga via Emacs 28.0.50, Org release_9.3.6-438-g5b9698
