问题描述
我们目前有一个Exchange 2003环境，有5个邮箱服务器和1个前端服务器。我们想介绍一个2010 Exchange MBX服务器。那可能吗？我们是否只使用CAS / HT安装MBX角色？

推荐答案
您需要在Exchange 2010中拥有MBX，CAS和HUB三个，否则它们将无法正常运行。
You need to have MBX,CAS and HUB all the three in Exchange 2010 else they wont be functioning without any one of them.
您可以在Exchange 2003服务器环境中引入Exchange 2010服务器
You can introduce Exchange 2010 server in Exchange 2003 server environment
确保您至少拥有Exchange Server 2003 SP2其他服务器不允许您安装Exchange 2010
Ensure you have at-least Exchange server 2003 SP2 else the it wont allow you to install Exchange 2010
您只能在以纯模式运行的Exchange 2003组织中部署Exchange 2010
