Trying to renew / create a new Self Sign certificate on Exchange 2010 running on Windows SBS 2011 Standard.
Followed this guide to created the new certificate:
After completing the certificate request the certificate disappears from within Exchange Management Console.
I researched this and found this guide:
I ran the certutil -repairstore my "SerialNumber" command
Then attempted the Enable-ExchangeCertificate
But I end up with the error:
The certificate with thumbprint XXXXX was found but is not valid for use with Exchange Server (reason: PkixKpServerAuthNotFoundIn
I have not been able to find a solution when I searched for this error.
