OWA is not that hard to setup. I use it and absolutely love it.
I would take a look at www.4smartphone.net. I have been using mailstreet.net for two years but switched to 4smartphone.net about five months ago and could not be happier. They support the usual owa, outlook over http, and best of all active sync direct push support for smartphones.
They even accept PayPal and their support for getting things setup is amazing.
Brenton: I checked out 1and1: You have to live in the US or the UK to register ::(
Jeff: 4SmartPhone.net sounds very nice! I may give them a try!
It's funny - I did *exactly* the same thing. When I realized what a shocking sysadmin I was, I moved to Gmail and have never looked back. They've got a calendar now, what else do you need? ;o)
I like Intermedia.net.
