Programmatically how to set Outlook message replied or forwarded state

Question

I am writing a conversion utility to convert messages from different client to Outlook, need to set replied/forwarded properties from the original message to converted Outlook message.

I used Redemption (http://www.dimastr.com/redemption/home.htm), unfortunately could not locate any replied/forwarded property in API documentation & OutlookSpy. Any suggestions about how to set these properties so Outlook client show appropriate replied/forwarded icon?

Thanks

You need to set the PR_LAST_VERB_EXECUTED and PR_LAST_VERB_EXECUTION_TIME as well as PR_ICON_INDEX MAPI properties - have a look at a replied or forwarded message with OutlookSpy (click IMessage).
