I'm moving from qmail to the free version of Google Apps for my personal domain. I'm moving, and losing my FTOH solution (and they didn't care what I did...) It offers 100 free email accounts, 6.5g of storage per email account, calendars, contacts, google talk, docs and sites. Gmail mobile access for Blackberry. Google sync for Calendar on Blackberry. I really just wanted an imap mail server solution, but thought I would try it out until I get moved and see what I have at the new location. No hardware, no software. I don't see anything about Outlook using google calendars, but I've only just set it up.... Maybe it'll do what you want....
