We're looking for hosted exchange service, we have 6 e-mail accounts that we will need to setup, as well as multiple distribution lists (around 20 or so).

I expect to have the ability to share calendars and contacts.

We're currently hosting our exchange with someone else, and we will want to move over our inboxes to the new company.

Any suggestions? I'm not looking for the cheapest solution, I was something rock solid, that I'm not going to have to worry about.

Check out solarvps.com they offer HE at great pricing and reliability.

I ran across SherWeb today too, have you had any experience with them at all?

I like how they have a white label reseller option - manage all accounts under one login.
