背景：
每天早上需要发站会纪要，纪要内容为组员昨日的工作完成情况，工作完成情况需要从每个组员的exchange邮件中选择昨日发的日报邮件，提取信息，因组员很多，每天这种重复的复制粘贴操作很麻烦，就想到了用java写个程序来完成这个事。
概念：
exchage 与 outlook
Exchange是服务器端的软件，而Outlook是其客户端的软件。只是Outlook不仅仅可以作为Exchange的客户端，还可以接收其他支持Pop3等的邮件，当然，Exchange邮件接收方式也不仅仅局限于使用Outlook，你也可以使用Foxmail等其他软件，也可以通过Web方式使用OWA方式接收。（PS：在网上搜索API的时候千万不要搜outlook相关的api，因为是针对exchange服务端进行邮件的操作，而非outlook，虽然我们在客户端使用的outlook）
方法：
- 使用微软的第三方库OfficeDev/ews-java-api 来实现exchange邮件相关操作，Github：https://github.com/OfficeDev/ews-java-api
- 使用Jsoup库来实现对邮件里的html内容进行解析及替换，Github：https://github.com/jhy/jsoup
步骤：
- 连接exchange
- 查找自己邮件中的组员邮件，并保存
- 查找日报模板邮件，并在指定位置替换成组员邮件中的信息
- 发送邮件
