Hi anantha, Get the new domain to point at your ip adr. (the same your are using now). Set the exchange 5.5 so it can get the mails for the new domain. On the user create a new e-mail adr. user@xxxxxxxxxxxxxx <mailto:user@xxxxxxxxxxxxxx> an set it to replay adr. if you do that your user can still get mails form the old domain but when the user sent a new mail it sent with user@xxxxxxxxxxxxxx <mailto:user@xxxxxxxxxxxxxx> If you have a firewall you should have to open for the new domain. Hope it is understandable.
