I should have mentioned that our first Microsoft Certified Architect live meeting went really well; it was a smaller group so we got to lots of very specific questions about things like, for example, everyone's favorite: event sinks. A very big thank you is in order for Infrastructure Architect Scott Andersen for taking time to do two of these sessions for us.
The question we heard most was about the upgrade path from SBS 2003 R2 to Exchange 2007. If you are wondering that, too, here is the answer: There is no upgrade path for SBS exchange in the short term (no 64 bit sbs). You’ll have to wait for the new version of SBS in the future. Sorry guys.
