Thank you Devin. I couldn't find a group for the OWA users? (There is access list for every one in the security tab.)

But still for users inside = the web they should be able to see it? Or is it a common thing for users = accessing OWA from outside to see the public folders? (we have so many = public folders) I would imagine you could simple remove owa users from = having access directly through your exchange system manager under Folder = > Public Folders =20 - Typically when a front end exchange in the DMz zone does it = have 1 NIC (public one in our case) and the routing to the trust is done = through the firewall or does it usually have 2 NICs one on the trust and = one on the DMZ? What exactly are your using isa for? just the = firewall functionality of it? If thats the case I dont see why you = couldnt just use a single nic. =20 - Can I install OWA 2003 to be used with exchange 2000? No, = you'll need to upgrade exchange to 2003. Luckily a 2000 to 2003 upgrade = is extremely clean. =20 DM =20
