Answered SSL Certificate Question

    I have setup a new Exchange 2010 server and I am migrating from Exchange 2003. I have an internal domain name of 123.org and an external domain name of abc.org. I have created a certificate request and was attmpting to purchase the cert from Digicert. The rep at Digicert told me that I could not buy the SSL cert because my internal domain name of 123.org is a registered external domain name of another comapny.

    My problem is that I am not sure how to remedy this problem. The rep I was speaking with got in touch with his Exchange cert expert and they directed me to this article http://support.microsoft.com/kb/940726 and told me to change the internal settings to use the domain name of our external domain name which is abc.org.

    Will this work to fix my problem? And will this cause any problems on the internal domain name?

    Lastly, would it be best to purchase a wildcard certificate or a SAN certificate. It seems like it would be simpler to manage it it was a wildcard cert. Once the migration is complete I will only have one outward facing Exchange server, so hopefully there would be no security problems with using the wildcard cert.

    Thanks,

    Doug
