           lv_omail                TYPE ole2_object, "Outlook.MailItem.

CREATE OBJECT lv_ooutapp 'Outlook.Application'.

CALL METHOD OF

       lv_ooutapp

       'CreateItem' = lv_omail

     EXPORTING

       #1           = 0.

   SET PROPERTY OF lv_omail 'Importance' = 1 .

SET PROPERTY OF lv_omail 'Subject' = 'TEST'.

SET PROPERTY OF lv_omail 'Htmlbody' = 'TEST'.

* start outlook in display mode

   CALL METHOD OF

       lv_omail

       'Display'.

* Ausräumen

   FREE OBJECT lv_omail.
