PidTagBodyCrc Canonical Property

Applies to: Outlook 2013 | Outlook 2016

Contains a cyclic redundancy check (CRC) value on the message text.

Associated properties:
PR_BODY_CRC
Identifier:
0x0E1C
Data type:
PT_LONG
Area:
Exchange

Remarks

The message store can use any CRC algorithm that generates a PT_LONG value. It must compute this property as part of the IMAPIProp::SaveChanges method when the PR_BODY (PidTagBody) property has been set for the first time and whenever it has been subsequently modified.

A client application uses PR_BODY_CRC to aid in comparing message text strings contained in PR_BODY properties or their variants. Using this property, the client can quickly and easily detect when the message text has changed. It can realize significant performance gains by using PR_BODY_CRC instead of obtaining PR_BODY from the message store and comparing it with a local version.
