遇到过有人在文件服务器上新建共享文件夹，自己无法COPY文件，别人无法看到的情况么？？

那要留心下面这个图和文字：

The offline files stored on your computer will not be able to sync with the files on the network while offline from the network. When you connect to the network again and the offline files are online again, they will automatically sync any changes you have made while offline with the files on the network.

一般是下面这种状态，那就可以符合常规理性了。
