I have OWA working perfect but one last thing that was requested is to allow users to access OWA
via the https://mail.mycompany.com name from the inside just like they do on the outside?  How can I do this?
DNS?

Split DNS.
You will need to create a new DNS zone on your server for mycompany.com
This will need to contain the internal IP address and host of mail.mycompany.com
If you have any services outside, such as a web site, then add the hosts to the DNS with the external IP address:

www type A IP 1.1.1.1
mail type A IP 192.168.1.1
ftp type A IP 1.1.1.2

etc

It should be a primary, non AD integrated. The name should match your domain - domain.com or whatever. Transfers to other domain controllers only.
On the other domain controllers, set it as a secondary, non AD integrated. Same name, but point at your primary.

Ok I just created two new zones and called them what I was looking for:

www.newcompany.com
mail.newcompany.com

added the internal IP to each zone and they both work.  Is this the correct method?  I don't want any DNS problems with the network, is why i am asking.

If you already have a zone called mycompany.com then you just need to add a host to that existing zone.
Type A, name mail with the internal IP address.
What you have done isn't correct and you should delete them.

A zone contains just a domain name - not hosts.

Thus: host.domain.tld
www.domain.com

OK I added both the www and mail hosts to the primary zone with the private IPs and it works.
What was all the split DSN talk for?   Is this a split DNS?

Yes this is a split DNS.

A split DNS is where you have internal and external DNS services and different answers are given to the clients depending on whether they are internal or external to your network. Vital to allow the same name to be used both inside and out.

The most common use/request has been when using RPC/HTTP with Exchange 2003 so that the client machines don't have to be reconfigured when on the network.

Glad to hear that you have it working.

Simon.
