I don't know how you feel about blue collar, but if you want, need, or simply must have yet another email account, BlueTie is one to check out. BlueTie however, really is much more than just an email account. Not only is it free email with 5GB of storage per user (yes, more than Google so far), but provides unified calendar and other collaborative tools including shared file storage, an "enterprise" user manager, tasks, and a frighteningly Outlook-like calendar. Many features of BlueTie remind me of Outlook's meeting requests, contacts, calendar, and other features in fact. The free account limits you to 20 users, but who's counting? Small business owners and groups will love this app. It is AJAX based and looks good enough that I am considering putting my business on it entirely, since most of the app can be shared with all your people, contacts, calendar, and file storage. Did I mention that you can use your own domain with BlueTie, as well as the fact that it has Virus and Spam protection built in? Oh yeah, it has that too.
