In GETSIMPLEPATH/plugins/p01-contact/p01-contact.php file I put after this and it fixed my problem (now in Outlook 'name' appears correct and 'subject' and other fields appear correctly in utf-8
Code:
line 717 if(empty($name)) $name = $this->lang('nofrom');
Code:
$name = '=?utf-8?B?' . base64_encode($name) . '?=';if(empty($name)) $name = $this->lang('nofrom');
