Exchange 用户邮箱配额最大值修改。

参考：http://www.planetmagpie.com/itconsulting/technotes-120905.aspx
Windows Small Business Server 2003 安装程序为 Exchange 邮箱设置以下缺省配额：

达到该限度时发出警告 (KB)： 175000

达到该限度时禁止发送和接收 (KB)： 200000
如果用户需要非常大的邮箱，则可以更改该配额，
但是最大配额只能达到2097151KB
这是服务器缺省限制的。如果你在以上2个输入栏中输入超过2097151的值，就会收到错误信息：
“The value for 'Issue warning at (KB)' is not valid. Specify a value from 0 through 2097151.”
解决办法：
用ADSIEdit 工具修改邮箱存储限制.
