18.104.22.168 PidTagSubject Property
Type: PtypString ([MS-OXCDATA] section 2.11.1)
The PidTagSubject property ([MS-OXPROPS] section 2.1104) contains the full subject of an e-mail message. The full subject is a concatenation of the subject prefix, as identified by the PidTagSubjectPrefix property (section 22.214.171.124), and the normalized subject, as identified by the PidTagNormalizedSubject property (section 126.96.36.199). If the PidTagSubjectPrefix property is not set or is set to an empty string, then the values of the PidTagSubject and PidTagNormalizedSubject properties are equal.
