Remarks
The message
store can use any CRC algorithm that generates a PT_LONG value. It must compute
PR_BODY_CRC as part of the IMAPIProp::SaveChanges method when the PR_BODY 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 textHL_DCQ 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.
