hey all, we have several public folders in outlook and if you go into any one of them that contain items, those items cannot be opened by anyone. permissions are there for those who need them. we are running windows 2000 server farm with exchange 2000. i am the owner on most folders and when i try to open anything, it gives me the following error: "can't open this item, unknown error". i can delete items and put items in there but cannot open them or move them. please help!
