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.
so other companies don't see this main folder (and subfolders)
choose an admin by company who can create subfolders in this main folder
