        ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010);
        service.UseDefaultCredentials = false;
        service.Credentials = new NetworkCredential("admin@test.com.", "password");

        ImpersonatedUserId i = new ImpersonatedUserId(ConnectingIdType.SmtpAddress, "admin@test.com");

I had a similar issue. In my case, the problem was different licenses. License: "Exchange Online Kiosk" specifies: "Direct access to Kiosk user mailboxes via Exchange Web Services is not permitted." You can check differences between various license types here: http://www.office365advisors.com/exchange-licensing/
