javamail connect to imap over ssl to read mails

I want to read emails from exchange server over IMAP SSL with JavaMail API. I am using the following piece of code.

Properties props =System.getProperties();

props.setProperty("mail.store.protocol","imaps");

Session session = Session.getDefaultInstance(props, 开发者_运维知识库null);

Store store = session.getStore("imaps");

store.connect("server hostname","username","password");

But I am unable to establish a connection. All I get is following error.

javax.mail.MessagingException: sun.security.validator.ValidatorException: PKIX path validation failed: java.security.cert.CertPathValidatorException: timestamp check failed; nested exception is: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path validation failed: java.security.cert.CertPathValidatorException: timestamp check failed at com.sun.mail.imap.IMAPStore.protocolConnect(IMAPStore.java:618) at javax.mail.Service.connect(Service.java:291) at javax.mail.Service.connect(Service.java:172) at

I am not sure if there are any pre-requisite steps to be followed for establishing a connection.

Appreciate your help!

to which mail server u r trying to connect?? replace IMAPS with IMAP and try it.

If you really need to use IMAPS try this

Your particular error seems to indicate that your current SSL certificate is expired.

java.security.cert.CertPathValidatorException: timestamp check failed

You either need to renew your SSL certificate or configure your mail server to point to the correct one.
