BIs does work with OWA but I think the people who previously gave you that reply ignored the whole VPN issue. I don't think you can configure BIS to VPN for an OWA connection so I can't see it working in your case.
In general I strongly suggest avoiding Redirector or Mail Connector for reasons already stated but it might be your best bet for corporate mail.
