I do not generate a CSR from this Exchange 2010. because I already have a widecard certificate. (.cer+key file) Thank You P.S. I use OpenSSL command convert .cer to .PFX and import through EMC, but It doesn't work. I get error message "The Certificate Status could not be determined because the revocation check failed" Finally, I'm not sure my method is correct.

Please post the openssl command you used openssl pkcs12 -export -in certificate.cer -inkey privateKey.key ? If you double click the .pfx does it open correctly, does the cert mention it has a private key?James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

Hi amestechman I use same command. (openssl pkcs12 -export -in certificate.cer -inkey privateKey.key -out email.pfx) Thank You All Again. I configure the proxy bypass, It's worked.
