IMAP is on the way (I'm using it now) but not quite ready for showtime. If you'd like access to the upcoming beta email dave (at)hiri(dot)com.

That's very unusual, normally IMAP is the easy one and Outlook is horrendous. What does it use under the hood?

You're right. It is unusual. We went with Exchange Web Services first instead of IMAP. Our initial target market were larger companies and we wanted to have deep integration with their Exchange servers (Calendars, Contacts, etc).
