After moved user not able access there Outlook Web access mail from External URL http://mail.domain.com/exchange (From Internally users able to access Outlook Web Access mails) What is configuration i have do adding addition exchange server? (Outlook Web access)

When an Exchange 2003 server is a front-end server it acts as a proxy for OWA. When it is not, as in your case where it is a mailbox server, it redirects. When you're coming in from the outside, that redirect probably isn't going to work becuase you're not using the server name from outside. The answer is to deploy a front-end server.
