Microsoft Exchange 2003 Server Hosting Dedicated Manager Host Outlook 2000 2002 2003 XP Windows ASP. If you don't want to run your own Exchange and Blackberry server, here's an option.
Haven't heard much about this, but if you have a family and you really want shared calendar, then this would do it for you. $10/month/person for Exchange hosting, then $10/month/person for Blackberry and finally you'll need a $40/month/person plan with a carrier. So for $60/month/person, you'd be like any big corporation.
Main advantage would be shared contacts in the family and shared calendar.
