We're currently running SBS2003 and will be upgrading both our server hardware and OS. We only have about 45 employees so Small Business Server is the most cost effective solution for us. I know that SBS 2008 comes with Exchange 2007, but since Exchange 2010 is out I was hoping to move us over to that version instead of 2007.
I have two questions...
1) If I installed SBS2008, could I install Server 2008 R2 on a second box (virtual machine) and put Exchange 2010 on it?
2) If the above is possible, would the SBS user CAL work for Exchange 2010? Or would I have to buy Exchange 2010 user CAL's in addition the SBS user CAL?
Thanks for any insight. We are unfortunately unable to wait until SBS7 comes out - although the next best option would be software assurance if this can't work. When you add on the extra cost for SA though, you almost reach the cost of just moving off SBS entirely.
