There were some great pointers in the session, though very few of them apply to an environment where you have fewer total mailboxes (~600) than MS puts on each cluster node (~4000).
I did get a bit of a relaxation moment at the beginning when the presenter asked how many people were still running Exchange 5.5, I’d say ~5% of the room raised their hands. We need to get off of it, but we’re not the last guy running it. Nobody was willing to admit they were still running Exchange 5.0, though I can’t imagine anyone is.
Many of these sessions are going to be best re-digested later once the conference DVDs show up.
Oh, and at lunch today they had Diet Mt Dew, YAY!
