PrivateKeyMissing when running Enable-ExchangeCertificate
Enable-ExchangeCertificate : The certificate with thumbprint XXXXXXXXX was found but is not valid for use with Exchange Server
(reason: PrivateKeyMissing).
At line:1 char:27
+ Enable-ExchangeCertificate -Thumbprint XXXXXXXXX -Services "IIS"
The above error can as a result of multiple reasons. CSR was created with IIS and attempted to be installed through the Exchange Management Shell (EMS), CSR was created in EMS on another Exchange Server, a damaged certificate, or Windows simply “forgets” where it placed the PrivateKey for the certificate. It doesn’t happen all the time, but sometimes the error can be a nuisance.
