计算当前Exchange 2010 数据库的用户使用情况

发布于

> 今天在微软的galary 中闲逛，发现了一个PS脚本，是导出当前的用户数据大小的值的，和对比一段时间数据库大小的值。我们现在不需要对比，只需要得出当前的用户的几个指标，因此我将这段PS代码修改了下，就不再需要利用EXCEL 做数据大小的计算了，代码如下，大家可以把这段代码COPY 到一个NOTEPAD中，然后保存为PS1即可。

把他保存为后缀为PS1的文件，保存即可。我们将文件保存到服务器上，然后以以下方式运行：
就会生成相应的CSV文件，我们文件内容如下：
然后我们用EXCEL 打开，可以很方便的处理相关的数据了，不再需要通过EXCEL 进行很繁琐的运算：
