I have purchased a 3rd party certificate from godaddy.com and am having a hard time getting it working. From the Exchange Management Console I click on "New Exchange Certificate" and then create my CRL. I submit to godaddy, download the crt file and then complete the process to import the certificate. It seems to work fine however I get the error "The certificate is invalid for exchange server usage".
Does anyone know what may cause this? I have also tried doing this using the Exchange Management Shell and still get the same error.
Thanks in advance.
