I think you just need Exchange 2007 SP1 RU9 or SP2 to support 2008 R2 DC's. If
it's a fresh install, you might need to start with 2007 SP2.

Ok I found my answer, exchange 2007 is not supported with 2008r2 servers. It
looks like there is some xml fix, but I think I have to also go back and
create a new vm with just 2008 not 2008r2 as that doesn't appear to be
supported either. I guess I should have thought to look this up beforehand J
