Please check this docshttp://technet.microsoft.com/en-us/library/aa997232(EXCHG.65).aspxYou can use any certificate that will be valid and trusted by your clients

You can follow the following 2 articles to use RPC over HTTPS with a certificate for your own local CA http://www.msexchange.org/tutorials/Outlook_2003_Connect_Exchange_2003.html http://www.petri.co.il/how-can-i-configure-rpc-over-https-on-exchange-2003-single-server-scenario.htm

Hi Sandeep, Here are three requirements for certificate: 1. Trusted Root Certificate - If you are using an internal CA or self signed certificate, you must install the CA Root certificate on client. 2. Server Host Name - The server's external host name must match the name specified in the server certificate. 3. The Valid Date - The certificates have a valid start day and end date. The certificate must not have expired. Regarding the certificate, you could install a internal CA and issue a new certificate. Regarding the RPC Over Http deployment, please read the guide provided by the friends above. Thanks, Elvis
