Sorry I haven't posted in a while, I've been extremely busy on a really great project. I'll be posting at length on that in the near future. For this post, I just wanted to point you to an article over on the Exchange team's blog about processor an memory considerations for Exchange 2007. I'm currently implementing Beta2 for the project mentioned above so this is very timely information. With all the talk of Vista and Office, Exchange is somewhat under the radar right now but this is a very significant release.
