And the file Emacs.org has such structure:

* Emacs ** INBOX *** blabla ------------
It doesn't work, the error message is "progn: Heading not found on level 3: INBOX".
To me, it seems Emacs was trying to find the headline (3rd level) with name of INBOX. But according to my configuration, it should go and find the head of 2nd level. Could anybody give me some hint why it behave like so?
