My company's exchange server is behind a nasty firewall and protected by SSL VPN, which has no client for the iPhone. This leaves me with no push email through activesync as our exchange has no public interface other than through the SSL VPN.

I know in the beginning of MobileME's life it was not possible, but I am hoping things have changed. Is there any way I can sync my outlook - exchange emails calendars with MobileME and onto the iPhone?
