小编这两天整理共享排错贴时发现，居然没有Exchange2013的case，小伙伴们也惊呆了。借着中元节的晚上不敢出门就在家更新一篇。
广州一同行前些天求助，说他们家的exchange2013安装失败了。报错如下：
我问他要exchangesetuplog，他贴给我

这个错误经查是可以忽略的。。。在查不出任何环境问题的情况下，我大胆地直接安装Exchange2013了。这里似乎有个陷阱，按照exchange2013的安装向导直接安装就会出现如第一张图的报错。必须先完成两个准备工作： Import-Module ServerManager

装好之后，配一个send connector就可以外发邮件了。
该同行还有安装Exchange证书的请求。但系统又报错了：
考虑到之前同行说在Exchange服务器上安装证书
服务器的时候系统崩溃了。我不大敢往
邮件服务器上装CA角色。所以建议他起一台服务器做CA。甚至不用配置达到域功能级别，做个成员服务器就可以了。
他听取了我的建议。上图的报错是因为在申请证书时直接选择了在邮件服务器上生成exchange证书，然而Exchange subsystem的账号在共享的位置上又没有读写权限。
用成员服务器建立CA的好处是不用怕影响到其他应用。而且选择的服务器不用达到域的功能级别。
在Exchange服务器上生成证书请求后，发送到
https://CASERVER/certsrv上，获取到证书，然后将其为IIS，smtp或者POP启用。这里插一句话，自签名的证书是不能用在
Outlook Anywhere上面的（Outlook2010及以上版本），哪怕是手动在客户端安装根证书。
当然如果CA服务器不活，证书就会立马变成无效状态。
整个CASE解决下来没什么难点，说明Exchange的发展趋势是越来越简单化大众化。
