问题

由于公司邮箱并未开放POP3收信端口,但配置exchange后,手机邮件客户端可以收发邮件,因此决定使用exchange协议收发邮件。但测试过程中发现登录时反复提示“440 Login Timeout ”错误,用户名密码并没有出错。

解决方案

OWA(Outlook Web Access)提供的EWS(Exchange Web Service)的协议地址原来是https://Exchange邮件服务器名/EWS/Exchange.asmx,修改后即可登录了。

代码

官方文档地址
项目中添加ews-java-api.jar后即可,maven项目中添加

<dependency>
    <groupId>com.microsoft.ews-java-api</groupId>
    <artifactId>ews-java-api</artifactId>
    <version>2.0</version>
</dependency>

工具类代码如下:

import microsoft.exchange.webservices.data.core.enumeration.misc.ExchangeVersion;
import microsoft.exchange.webservices.data.core.enumeration.property.BodyType;
