Currently we have a front end and back end 5.5 server(s). We just upgraded AD to 2003 and have our first 2003 DC. We prepped AD for Exch 2003, setup ADC, installed the first and new Exch 2003 server into the existing 5.5 site. We tested replication and is working. We tested moving a mailbox, that went fine. However the problem is that a user on the Exch 2003 server can send mail to a user on the Exch 5.5 but not to the internet and the users on Exch 5.5 can not send to the users on Exch 2003. Internet users can not send to users on the Exch 2003. Any ideas?
