Easy1Indian - can't agree more - I posted a similar comment in the MS Newsgroup - public.Excahnge.setup - topic - Where do you sign up for the exchange 2007 SP1 beta?
Someone from MS said - they wanted feedback on Exchange 2007 I said some similar things and they said there are no issues with removing Exchange 2007, it doesn't do anything to exchange 2003 and I was made to feel like an idiot because I didn't want to use the powerscripts since I was happy with managing through ESM in the past 3 versions. They didn't seem to think there were any issues with public folders either. I guess since I'm not a programmer my opinions didn't count for much. Hopefully you'll post this comment in that group as well.
