打开官方文档，发现全是C#的示例
我们的实际情况是：
-
开发端在MacOS
-
调试在Windows虚拟机，通过虚拟机连接内网，获取内网部署的Exchange Web Services数据
-
最终服务端需要运行在Linux上
为了多端兼容，而且对C#不熟悉，还好网上还能搜索到部分Java的示例，所以使用Java接口进行二次开发
主要开发功能是获取用户的日历数据，同步到公司系统，方便查看统计数据

这是一个简单的API，旨在轻松生成Microsoft Outlook邮件文件（.msg）。 该库基于并且是100％Java实现。
只需将jotlmsg.jar及其依赖项添加到您的类路径中。
如果您使用的是maven，则只需添加以下依赖项：
< dependency>
< groupId>ch.astorm</ groupId>
< artifactId>jotlmsg</ artifactId>
< version>1.7</ version>
</ dependency>
如果打算使用toMimeMessage()方法，则还需要以下依赖项：
< dependency>
< groupId>com.sun.mail</ groupId>
< artifactId>javax.mail</ artifact

最新推荐是使用Oauth令牌验证access,进行邮箱服务，可参考官网https://learn.microsoft.com/en-us/exchange/client-developer/exchange-web-services/how-to-authenticate-an-ews-application-by-using-oauth。第一步注册应用，获得client_id, tenant_id 和client_secret.第二步，获取token.
ews-java-api是一个非常好的解决方案，封装了 完整的api接口，可实现各类需求，但是，该方案只考虑了通过用户名和密码的方式来实现认证账户，用户的需求是通过OAuth来实现认证。通过ConfidentialClientApplication类来实现clientId、tenantId、secret三个参数OAuth认证，获取到token。读取outlook邮箱下的邮件内容，通过OAuth来实现邮箱认证。在本地中创建BearerTokenCredentials类。以下是官方的解决方案，
