Youtrack integration with Exchange IMAPS Follow

I'm trying to setup a mail integration with Exchange IMAPS (Youtrack 7.0).

I read the documentation and the forum but I couldn't figure this out yet.

Our exchange server use Go Daddy certificate.

On the Web page SSL Keystore I imported the PFX certificate used on the exchange server.

On the mailbox I setup:  IMAPS, port 993, and on SSL Key I selected the key that I imported.

When I click Test I got:

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

I appreciate your help, thank you.
