I have recently done an upgrade to exchange 2003 from 5.5.. Everything is Sucessful except the Public Folders. No One is able to access them. I checked permissions but its all good. I didn't have this problem until I switched to Native mode. I did however do test before then without the old server to make sure Exchange Worked properly. It did even after I removed the Site Replication and and Active irectory connector. the problem only started once I switched to natvie mode. Please help thanks in advance.
