SBS2008 and Exchange 2010

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.

Your going to run into lots of problems with SBS2008 and exchange server 2010.

I would just hold off until SBS7 it's built on Server 2008 R2 X64 and comes with Exchange 2010.

 
discard my post sorry about that.

Unfortunately that is not possible. We've been hitting the Exchange 2003 size limit for the past several months. Archiving has kept us going but the volume, types of emails, and management's decision to not limit inbox sizes will force us off 2003 soon.

I appreciate the alternate suggestions but we've explored our options and decided this is the best course of action. It simply costs more over the course of the server lifespan to use hosted exchange.
I have not worked with SBS and exchange in the same environment, demazter could probably answer this better,

But you could get a machine and  install Server 2008 R2 and have a DC and Exchange 2010 run on it (though it isnt by best practice but fully functional)

But then again sbs with exchange 2007 might be the best solution for the time being, later one you can just install exchange 2010 to co-exist with your exchange 2007. By doing this you can configure the exchange 2010 in the background to avoid any major problems, while end-user are located on exchange 2007

Part 2 though: if you run Exchange 2010 in a SBS network, do SBS CALs cover it or would you need Exchange 2010 CAL's?
