My another question is that:
Right now we have 1 domain with 1 exchange server 2003 , but we are going to add another domain because of users accessibility to both of them. ( The two domains are registered )
1) First af all, Should I set up another exchange server for the new domain ? and if not is it true one exchange could be set up for two domain ?
2) How can I see "From" option in OWA . Because our users have to select the domains with out log in/log off.
Awaiting for a prompt reply
