while trying to configure exchange to work with certificates issued from my internal MS PKI, I deleted the self signed certificates. and now I can't access exchange. the good thing is that this is not a production environment yet. I was looking around and I couldn't find a documentation on how to request certificates from an internal CA. and how to assign the certificate to exchange.
I need help regarding this, if any one has a working environment with CAS and MB on different server, how the certificates are assigned in IIS.
