OWA login problems

[kulagun]

I have been trying to figure this out for 2 days but now I need help.
On my server I installed exchange on a domain controller, the domain for 2000 is abc.com. My email domains are 123.com and xyz.com. When I create a user I can login under owa just fine, however when I change is email address to 123.com or xyz.com it won't work. I have to change it back to abc.com (which is just my 2000 domain)Does anyone know why?

Thank You

when you added those email domains on your recipient policy, did you allow it to propogate the address generation to all your users?

try to create a virtual directory for your 2nd email domain. go to microsoft exchange>system manager>server>Protocols>HTTP>Right click to Exchange Virtual Server then create a new virtual directory then poin this directory to your 2nd domain.
