Question

我必须使用java代码连接到一个Outlook 365帐户，并从该帐户读取INBOX的电子邮件。

错误：

无法连接到邮件存储:: javax.mail.MessagingException：连接失败;嵌套异常是： javax.net.ssl.SSLHandshakeException： sun.security.validator.ValidatorException：PKIX路径构建失败： sun.security.provider.certpath.SunCertPathBuilderException：无法找到要求的targetCould无法连接的有效证书路径消息存储:: javax.mail.MessagingException：连接失败; 嵌套异常是：javax.net.ssl.SSLHandshakeException： sun.security.validator.ValidatorException：PKIX路径构建失败： sun.security.provider.certpath.SunCertPathBuilderException：无法找到所请求目标的有效证书路径

我不确定需要在Web逻辑服务器上导入哪些证书，以便My java代码可以在没有SSL握手错误的服务器上运行。

Java代码：

                            part.saveFile(saveDirectory + File.separator + fileName);
                        } else {
                            // this part may be the message content

                        }

                    if (attachFiles.length() > 1) {

            store.close();

            System.out.println("Catch All" + ex.toString());
        } catch (IOException ex) {
            System.out.println("Catch All" + ex.toString());
        } catch (Exception ex) {
            System.out.println("Catch All" + ex.toString());
        }
    }
}

你们可以帮助我吗？
