Exchange Server 2016 CU9积累更新正式发布

Exchange Server 2016 CU9 已发布到 Microsoft 下载中心！由于 Exchange 2016 采用与 Exchange 2007/2010 不同的服务策略，使用「积累更新（CU）」方式进行更新，而不是以前所用的「汇总更新（RU/UR）」。Exchange 2016 积累更新（CU）采用了可完整安装方式，能够用于直接安装新服务器或对已有 Exchange 2016 服务器进行升级更新。

Exchange 2016 CU9 的命名为 ExchangeServer2016-x64-CU9.iso，其版本号为 build 15.01.1466.003，详细信息包含在  KB4055222 中。
