Do you mind sharing your solution?
I understand on the exchangeexpert you shared to you follow the instruction here:
http://my-virt.alfadir.net/2012/05/generate-view-5-1-certificat/
But I'm still a bit confuse since he was using Microsoft CA cert and we are on GoDaddy.
I also tried to follow the KB and still lost because it also us Microsoft CA cert.

When you downloaded it from GoDaddy, which cert did you pick?
I usually used Tomcat but it's different now I guess?
I converted the Tomcat to p7b certificate and when I ran the keytool command it says Input not an X.509 certificate.
If you could share your success, it'll be much appreciated.
Cheers.
