How to Obtain a Server Certificate from a Certification Authority
You can obtain server certificates from an outside certification authority (CA), or you can issue your own server certificates by using Microsoft Certificate Services.
Before You Begin
Obtaining a server certificate from a certification authority is one step in the process of configuring SSL. For an overview to the procedures you must follow to configure SSL, see "How to Use SSL to Secure the Communications Between the Client Messaging Applications and the Exchange Front-End Server" in the Exchange Server 2003 Client Access Guide.
For questions you should consider when selecting a certificate authority, see "Obtaining Server Certificates from a Certification Authority" in "Securing Your Exchange Messaging Environment" in the Exchange Server 2003 Client Access Guide.
Some certification authorities require that you prove your identity before they will process your request or issue a certificate.
