Add New Domain to Exchange 2010 but still route mail to external server
Posted on 2014-02-11
We have purchased a company that currently is using SBS 2003 and has Exchange email accounts.
We are going to migrate them to our Exchange 2010 server.
In the mean time, I want to go ahead and start the setup of the mailboxes on the 2010 server but I'm afraid if I add the new domain and mailboxes to the server, the mail from internal users will go to the new mailboxes I've setup on the 2010 server.
Is there a way to avoid this as the migration is going to take a few days and I want the mail from internal users on the 2010 server to still go to the mailboxes on the 2003 server that users will still be using until completely migrated?
