I am about to move one of my newly acquired sites into our Exchange organization. The Exchange 2003 server is in place and the accounts have been created. Currently DNS still points to their old Exchange 5.5 server and this is the server the users are logging into.
Since it is a small office that is using Outlook to connect via POP, we are going to migrate the PST files within Outlook to their new mail profile therefore populating the new mailboxes.
Problem is, when internal people try to send mail using their internet address, the mail attempts to send to the new Exchange server, even though SMTP is turned off and there is no Recipient Policy for the domain name. The new Exchange server is actually turned off but it still queues to the new server.
How do I disable this until I am ready to migrate? I need people sending mail to email@example.com to be able to send to the old server until they are moved over.
