Exchange 2016 CU9 已发布

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

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。
