我正在尝试使用EWS Java api从我的java Web应用程序发送邮件。但是在发送邮件时收到错误。我们安装了Exchange 2013服务器。
这是我的代码
ExchangeService service = new ExchangeService();
ExchangeCredentials credentials = new WebCredentials("username","password");
service.setCredentials(credentials);
try {
service.setUrl(new URI("host/ews/Exchange.asmx"));
service.setTraceEnabled(true);
EmailMessage msg = new EmailMessage(service);
msg.setSubject("Hello world!");
msg.setBody(MessageBody
.getMessageBodyFromText("Sent using the EWS Managed API."));
msg.getToRecipients().add("emailAddress");
msg.send();
}
catch (URISyntaxException e) {
e.printStackTrace();
}
}
这是跟踪报告和错误日志
