We are just beginning to implement Exchange 2003 SP1 on Windows 2003 within our Exchange 5.5 organization. We have seven Exchange 5.5 servers. I've added the first 2003 server to an existing 5.5 site. Things are working pretty well, but I've just discovered that I cannot access Public Folders from OWA. I can get to my other folders fine, but when I try to access public folders I get the message "The page cannot be found" (error 404). I can see the public folder tree, but not any of the contents. I can access public folders fine from within Outlook. The public folders I am trying to access are on 5.5 servers. Any help??
