OWA has stopped working after i un-installed Mail Marshall exchange, i get the following error below when i test connectivity on testexchangeconnectivity.com site:
Testing the SSL certificate to make sure it's valid.
The SSL certificate failed one or more certificate validation checks.
ExRCA is attempting to obtain the SSL certificate from remote server exchange.questek.co.za on port 443.
ExRCA wasn't able to obtain the remote SSL certificate.
The certificate couldn't be validated because SSL negotiation wasn't successful. This could have occurred as a result of a network error or because of a problem with the certificate installation.
Please assist Thanks,
