18.104.22.168.1 PidTagNormalizedSubject Property
The PidTagNormalizedSubject property ([MS-OXCMSG] section 22.214.171.124) specifies a combination of the full name and company name of the contact. This property is computed by the client according to an implementation-dependent algorithm that uses values of the PidTagGivenName (section 126.96.36.199.6), PidTagMiddleName (section 188.8.131.52.5), PidTagSurname (section 184.108.40.206.4), PidTagGeneration (section 220.127.116.11.2), and PidTagCompanyName (section 18.104.22.168.2) properties. The client uses the value of the PidTagNormalizedSubject property as the caption of the window displaying information about this contact. The value of the very similar PidTagDisplayName property (section 22.214.171.124.8) might contain characters that cannot be displayed as a window caption.
