Installed one new exchange 2007 server into exchange 2003 organization, with just one 2003 server. WIll co-exist only for short time < 1 month. Small office, 25 users. Moved two mailboxes from 2003 to 2007, they can receive email fine, from internal and external. They can send receive between each other just fine. But they cannot send email to any mailboxes on the 2003 server or out to external domains. The bi-directional routing connectors were created during install. Everything I have tried did not help, and I'm back to where I started. I saw something about suppressing Link State ? Any Ideas? -- Thanks in advance....
