现在单位里用的还是Exchange2003的邮件系统，但是今年有计划升级到Exchange2007或者Exchange 2010，对于Exchange2007，目前大方面的事情都已经了解了，包括其对Exchange2003最大的改变----5个角色的设置，以及对存储的要求显著降低。
现在开始对Exchange2007的小的细节方面进行学习了，否则到时现查资料估计就来不及了。
如何检查安装的Exchange2007是什么版本
方法1： 命令行方式
在Exchange 2007 服务器上，进入命令行模式，进入Exchange Management Shell，执行以下命令;
Get-ExchangeServer | fl name,edition,admindisplayversion，执行后如图，可以看到Exchange的version
方法1： 注册表方式
可以通过查看Exchange服务器的注册表的键值来查看Exchange2007的版本，具体的键值为：
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Exchange\v8.0\<Exchange角色的名称>\ConfiguredVersion
查询结果如下图，我在这台Exchange2007服务器上装了3个角色，任意查看一个角色。
下面是具体的版本号对应的Exchange版本，自己对以下就知道你的exchange2007服务器现在是什么版本了。（摘自： http://technet.microsoft.com/en-us/library/bb232170(EXCHG.80).aspx）
