I run Exchange 5.5 on NT Server 4.0. The server is at SP5 and Exchange is at SP3. I have created several contact lists in the public folders section giving myself “Owner” permissions, and everyone else “Reviewer” permissions. My problem is that items seem to disappear from within these folders. I have not deleted them, and no-one else has permission to delete items. Can someone tell me what is happening and how to fix it?
