At the office I've noticed that I can't access certain windows folders even if the permissions are set to read / write. This seems to happen to folders my co-workers have added. When someone else on a mac adds a folder I can't add files to it. When I add a folder myself, this co-worker can add files but he on his turn can't add files to folders co-worker number 3 had added. When I view all folders with Info I can see that permissions are set to read/write, so we should be able to save something to folders we haven't added ourselves. I can add a folder myself and add something to this folder. IT has checked the network drive in question and we should have complete access to the entire network drive. What could be wrong?
