Question : New SSL Certificate for Mail Server

Hello Experts:

Recently, I have switched one of my companies that was running Exchange 2003 on a SBS 2003 Server over to a server running Exchange 2007.  I want to RPC over HTTP on the Exchange 2007 server--the question I have is can I use the SSL certificate that is on the SBS server or do I have to get a new SSL cerificate for the Exchange 2007 server?

Thanks for the help

Answer : New SSL Certificate for Mail Server

I've just tried it myself and it would appear that your certificate was issued by a company which Internet Explorer does not trust. Basically, the issuer's root CA certificate isn't installed in the trusted certificates store.

Before you can do RPC over HTTPS then you will need to get this issue sorted out. GoDaddy have good deals and aren't as expensive as Verisign: https://www.godaddy.com/gdshop/ssl/ssl.asp?ci=8979
You could try importing the certificate to the trusted certificates store so it is trusted and the error is suppressed, but I'm not even sure if RPC/HTTPS will work then. A cheap GoDaddy certificate is well worth it!
