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KB 4055222

# 1 NOTE  

值得注意地方 Exchange 2007 产品不再受支持，安装惯例，一旦产品退出生命周期，微软不会再提供补丁更新

Exchange Server 完全支持TLS 1.2 协议

随着2018年3月的更新，Exchange在所有支持的Exchange版本上完全支持TLS 1.2，如客户希望实施TLS1.2 时，建议先阅读发布指南，详细可在此处查看

https://blogs.technet.microsoft.com/exchange/2018/01/26/exchange-server-tls-guidance-part-1-getting-ready-for-tls-1-2/

支持.NET Framework 4.7.1

.NET framework 4.7.1完全支持。目前这是一个可选项目，2018年6月的季度版本开始，Exchange Server 2013和2016安装将需要.NET Framework 4.7.1。建议客户应计划升级到.NET Framework 4.7.1，以避免阻止安装Exchange Server 2013和2016的6月2018年季度版本。

Active Directory林功能级别

根据Exchange Server 2016的Active Directory林功能级别，宣布Exchange Server 2016将强制执行Active Directory的最低2008R2林功能级别要求。 Exchange Server 2016的累积更新7开始实施此AD DS要求。
