The Exchange 2010 Beta was released just the other day. I encourage everyone to read more about all the new features and improvements that we've made here:
Just some of the cool new features:
- No more Storage Groups
- No more LCR/CCR/SCR
- New, simplified high availability with Database Availability Groups
- All new Outlook Web Access, and integration with OCS
- and a whole lot more!
You can download a copy of the beta here and give it a try in your lab:
