I hv compleated  HMC 4.5 setup for Exchange 2007 hosting in a  testing environment . Have few issues & need help in fixing them ,

1. When I create a "New Organization" , The organization name used with .com suffix for UPN suffix by default . I want to provide the cutomer public domain name as the login name to OWA . ex . if the customer email is suzanap@rhac.edu.au , I want to provide the same as the login name . Hence how can I customize the UPN suffix ?

2. When I create a new user "pre-windows 2000 login name" appears suffixed with the domain name . Ex for the user suzanap@rhac.edu.au , pre windows 2000 login name  is cavhost\suzanap_rhac.edu.au  ( correct would be cavhost\suzanap )
(CAVHOST is the parent domain name)  how can I fix this ?

3. How can I select the mailstore manually  when creating the mailbox

4. I'm not able to get the OAB for any Organization I create . How can I start troubleshooting this .
