Need to get Type of operation performed on Mail

I want to generate EmailThreading ..

Can some one advise, which field i can use from Redemption to get TypeOf(Replied,Forwared etc..)for given mail chain.

Let's say for the case,

• A send mail to B.

• B forward that mail to C.

• C forward that mail to D.

• D Replied to mail A.

which field of redemption i can use to get Reply,Forward type detail which can be use in generation of Email Threading.

There are few fields i have searched as below, PR_LAST_VERB_EXECUTED

PR_LAST_VERB_EXECUTED, this field having value for last action that mean if B send mail to C, this field having value for Mail of B user, but no value can be found in this field for c user Mail.

Can we capture accurate information of MailType using subject prefix or anyother property using Redemption??

Please suggest.

Thanks

You can try to look at the PR_IN_REPLY_TO_ID MAPI property (take a look at the messages with OutlookSpy - I am its author) to figure the reply/forward chain. You can also check out the PR_CONVERSATION_INDEX property to see if the threading is correctly captured there.
