PidTagOriginalSubject Canonical Property

This content is outdated and is no longer being maintained. It is provided as a courtesy for individuals who are still using these technologies. This page may contain URLs that were valid when originally published, but now link to sites or pages that no longer exist.

Contains the subject of an original message for use in a report about the message.

Associated properties:

PR_ORIGINAL_SUBJECT, PR_ORIGINAL_SUBJECT_A, PR_ORIGINAL_SUBJECT_W

Identifier:

0x0049

Data type:

PT_STRING8, PT_UNICODE

Area:

General messaging

These properties are originally set to the same value as the PR_SUBJECT (PidTagSubject) property.

The subject properties are typically small strings of fewer than 256 characters, and a message store provider is not obligated to support the Object Linking and Embedding (OLE) IStream interface on them. The client should always attempt access through the IMAPIProp interface first, and resort to IStream only if MAPI_E_NOT_ENOUGH_MEMORY is returned.
