I've found a couple questions on this subject but none that adequately address the problem. I have an Exchange environment all setup in a hosting scenario. Recipient policy, GAL, OU - all setup. My problem is public folders. How do I set those up so that one company can't see the folders of another company? I've found incomplete information on a few web sites (including this one) but nothing that gives a step-by-step understanding of what to do. I have tried MANY things and just need some solid instructions.
