To Filipp Geyer: It's impossible to integrate exchange with the current SQL Server. You would have to modify the SQL's design. It is a very bad ideea to modify SQL Server just to adapt it with a new Exchange. So, i only see 2 options: they integrate a SQL-like engine into Exchange, replacing the ESE engine or they make a new product, with separate licensing, "SQL Server for Exchange" :)
Unfortunately Microsoft doesn't seem to understand that there is a big market for Exchange in SMBs. Exchange is a complex product, which is good both for SMBs and for large companies; but it's very expensive both to license, and to maintain.
Of course, from the business point of view, i think they would choose the second option.
To the Exchange Team: When are the E12 SP2 and E14 Beta 2 scheduled to be released?
Microsoft
