Thank you Clark,
However I´m afraid I have a set up issue. I today sent a message with several blind copy receivers, none as copy, and myself as main receiver. When I open up the sent one or the original returned to my inbox (not just in preview), none of them show spaces for neither Copy or Blind copy, just Receiver (with my own name), date, subject (and maybe some more - I do not dare to leave this window to check exactly).
Normally I would be able to read a program version number (2013) under Help, but it leads to webb support. I checked both my installed Outlook and the cloud version. I have automatic updates.
