The Mail you show is a so called PGP/MIME mail.

We are well aware that GpgOL for Outlook 2010 and later versions only provides a
very basic OpenPGP support and no PGP/MIME Support. It is mentioned on the
website and in the documentation.

We are hoping to develop this but this is a huge Feature and very problematic to
implement given Outlook's extension API.

You may want to try out the latest 1.3.0 Beta version which supports reading
PGP/MIME mails. See:

PGP/MIME is supported since Gpg4win 2.3.
