tt: Thanks for the feedback. We will certainly think about that usage scenario for the monthly calendar as we design it for OWA2007. Most users of the monthly calendar have a different requirement from what you describe. They have a requirement that the whole calendar should fit on one screen at the same time so they can get a quick overview of what's going on that month. I can't promise we can address both these conflicting requirements, but I can assure you we will try to come up with a good UI doing just that.
Richard: If you'll be coming by TechEd in Boston in June I think there's a chance you maybe able to get your hands on a build of Exchange12. Otherwise we are aiming to have Exchange12 Beta2 out for public review this summer.
