Question : How to create subdomain for example mail.company.com?

Want to offer the users easy login to OWA by using https://mail.company.com

Contacted my ISP and they have added mail.company.com to my domain. In the firewall I have pointed the IP-adress to the OWA on the mailserver.

What to do with the DNS and how to do it?

Then what you want to do is make OWA be the default page, so that you don't have to enter /exchange correct?
