Simon Hackett of Internode (more like, Mr Internode) on why Internode has shifted their internal staff email from an open-source IMAP server to Microsoft Exchange 2007 earlier this year. 

I think the missing link for me, despite Snow Leopard, is still Outlook Web Access. It’s still not at feature parity, and I don’t mean trivial features! On Exchange 2003, you can’t even change your password on OWA Basic.. much less the email rules that he mentions. I need to have a look at Exchange 2010 soon. 

There’s this thing called outlook.com, similar to Google Apps but with a distinctly Microsoft flavour and harder to use.
