I currently have a CAS which has an existing Verisign certificate.
When I attempt to issue a new certificate to the company wildcard one it says that the certificate thumbprint already exists.
I have installed the intermediatry certificate.
If I run remove-exchnagethumbprint blahblahblah then the object isnt found.
If I run get-exchangecertificate then the thumb print isnt listed.
How can I upgrade my cert ?
