I am in the process of setting up a fresh install of Exchange 2013 in a new domain. The domain is ad.LegalName.com. I have setup the Exchange Virtual Directories (OWA, ECP, etc.) to be https://mail.DivisionName.com/
In order to allow my internal users to use https://mail.DivisionName.com/owa
to access their email in their browser, I created an Alias / CNAME in the DNS Manager on the domain controller. Since there was only one Forward Lookup Zone of ad.LegalName.com, I had to create a second Forward Lookup Zone of Division.com and create the Alias there for mail.DivisionName.com.
This seems to have worked. Within the network, I am able to go to https://mail.DivisionName.com/owa
and it brings me to the OWA login page.
Now for my questions:
#1 - Did I set this up correctly? I am pretty green when it comes to DNS configurations and such. I just want to make sure that this was setup properly and that I am not going to have any problems.
#2 - I am purchasing a wildcard SSL certificate for use on the Exchange Server. I am assuming that I will need to use DivisionName.com as the root domain for the certificate. While the Exchange server that the certificate will be installed on is part of the ad.LegalName.com domain, the site that the user will go to is mail.DivisionsName.com/owa
to access their mail. I just want to verify that DivisionName.com is the proper root domain to have the certificate issued to for use on the Exchange server.
Thanks in advance for all the help!
