PR_DISPLAY_TO is not settable.
NewMail event (unlike NewMailEx) does not pass the new message as a
parameter. How do you retrieve the new message?
Do you save the message?

My is ATL/VC2005. OnNewEmail to dispatch the event.
While OnNewEmail function were invoked, I tried the two methods:
1. ");
2. Get IMessage interface, then call SetProps() function with Tag
PR_DISPLAY_TO_A, return value's S_OK. But when i open the message, nothing
were changed.
What should i do then?
