Actually, when it is the COPR, that cannot be sent by email. COPR needs to be in original. Also, it is very possible that he doesn't get an email from them before issuing the COPR, since he is visa exempt and Vienna won't do a PPR. All he needs to land is his COPR and his passport.
Although, most visa exempt national get a request for a copy of the passport (bio data) to re-confirm identity with the VO and to make sure the COPR is issued in accordance to the details of the passport. But I'm not sure this is a requirement for all visa exempt passport holders.
@ little_apple: you should ask the senior members of this forum about the request of the PP copy. You haven't got that request, right? You just saw "decision made" on ECAS with the mention they sent you a letter about the decision?
