Question : Installing public SSL for Exchange 2007 server

Hi Guys,

Need some expert advise with a public SSL;

We have an Exchange 2007 server with a self-signed certificate being installed and setup a while ago.  However, we want to install a proper public certificate on the server.  Thus, discontinue to use the self-signed certificate.

1

Option 1

Will it be easier to use the name FQDN for the public certificate and "overwrite" the self-signed certificate with the same name?

2

Option 2

Or will it cause less problems and headaches to register a public certificate with a completely new FQDN and install the new certificate on the Exchange server as an additional certificate to the self-signed one?

doesnt' really mater, in both cases you can use only certificate per service

get a public certificate with the fqdn you need  i.e.

mail.domain.com (assuming this is your owa url)
autodiscover.domain.com
servername.domain.int (if applicable)

and then assign it to the IIS service
