First of all, thank you for your work in excorporate. I don't know what

I attach here the results of executing

(setq URL-STRING "https://correo.unican.es/ews/exchange.asmx")
     (progn
       (setq url-debug 1)
       (url-retrieve-synchronously URL-STRING)
       (dolist (p (seq-filter
                   (lambda (b) (string-match " *http*" (buffer-name b)))
                   (buffer-list)))
         (message "HTTP result buffer: \"%s\"\n%s"
                  (buffer-name p)
                  (with-current-buffer p (buffer-string))))
       "check *Messages*")
