My new install woes: SSL, OOA, autodiscovery

We are having a few problems reguarding the OOA in outlook 2007.
Ithis is my last resort, before I give up and call someone in.

We have a new exchange install,
We are using a ssl that we made. OWA work, Outlook anywhere works, OOA works via OWA.
Autodiscovery seems to work.
when I run a test e-mail autoconfiguration in outlook, here is what I get:

ProtocolExchange RPC
Server: internalservername.local
Login: myname
Availability Service URL: https://mail.myexternaldomain.org/ews/exchange.asmx
OOF URL: Https://mail.myexternaldomain.org/ews/exchange.asmx
OAB URL: https://mail.myexternaldomain.org/xxxxxxx-xxxxxx-xxxxx-xxx/..<<<....long string of chars
Auth Package:Unspecifed

Protocol: Exchange HTTP
Server: mail2.myexternaldomain.org <<<<<<<this should me mail.myexternaldomain.org....mail2 was temp.
Login Name: myusername
SSL: YES
Mutual Authentication :yes
Auth Package: Basic
Certifacte Principal Name: msstd:mail.myexternaldmain.org

Also  i noticed that get-antodiscovervirtualdirectory returns the server name, but no internal URL.

any advice would be great.
thanks
