We purchased a 3rd party SSl certificate and successfully imported it onto the CAS server where we generated the CSR. What we're trying to do now is export that certificate so that I can import it onto our 2nd CAS server. I ran the following command: Export-ExchangeCertificate -Thumbprint "included our thumbprint" -BinaryEncodedtrue -Path c:\certs\export.pfx -PasswordGet-Credential).password I put in a username and password but I'm getting the following error message: Export-ExchangeCertificate : Cannot gain access to the private key or it is notexportable, and as a result cannot export as PKCS-12.Parameter name: ThumbprintAt line:1 char:27 Has anyone seen this before? I need to install this cert on the other CAS server as well as our ISA server

Most CA charge you money when installing the same certificate on multiple boxes. Have you tried to export certificate with the certificate MMC snap-in?
