Hi All,
Due to the fact that we bought a new company we need to migrate the E2K13 Exchange setup (The mailboxes) to our main E2K10 setup.
Now the migration of the mailboxes are easy. But due to the fact that we can't migrate all mailboxes at once we need to keep the mail flow running. And the E2K13 Exchange server will be receiving the mail from the Internet. So the question is how to be able to deliver the mail to the mailboxes that we already moved to the E2K10 enviroment in the other domain (the migrated users will still have their SMTP domain attached to them) and also ensure that the users can send mails to all users in both enviroments ??
