PidTagOriginalSubject Canonical Property

Applies to: Outlook 2013 | Outlook 2016

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

Remarks

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.
