New certificate status is unknown on Exchange

I just order a new certificate from Entrust for my exchange server and webmail to replace the expired one, I’m able to install and enabled for IMAP, POP, IIS and SMTP, but when I use outlook, it shows “The security certificate has expired or is not yet valid” and when I run Get- ExchangeCertificate it shows “Status : Unknown” on the new certificate.  It seems outlook still using the old cert. How can I change the status? Please help, thanks in advance.

this means that Unknown   Exchange is unable to determine the type of certificate that is installed.
Please validate the certuficates have the private keys.
