Exchange 2016 CU9 已经发布到微软下载中心！ 有需要朋友可以自行可以下载了。Exchange 2016具有与Exchange 2007/2010不同的服务策略，使用累积更新（CU）补丁，而不是先前使用的汇总更新（RU / UR）。 CU是Exchange 2016的完整安装，可用于安装新服务器或更新以前安装的服务器。 Exchange 2013具有相同的服务方法。此版本包括以前发布的所有更新，修复了客户报告的问题以及新功能。

这是Exchange 2016 15.01.1466.003版本，此CU更新命名为:ExchangeServer2016-x64-CU9.iso，这使我们可以轻松识别安装，这点感觉很赞。该版本的详细信息包含在
