I want to move to exchange 2003 environment from my existing exchange 2000 by using the MAILBOX MOVE method as my existing hardware is very old one and I want to get rid of it.
STEPS TO BE PERFORMED:
recently I added the first new exchange 2003 server in my existing exchange 2000 organiztion which required me to update the schema of my existing win2000 AD by using the following commands:
setup.exe /foresrprep (Exchange switch)
setup.exe /domainprep(Exchange switch)
while all the above aforementioned commands successfully update the schema and other attributes required for exchange 2003 installation
Now I move 5 mailboxes from old exchange 2000 to exchange 2003 for testing purpose while later on I will move all of my mailboxes, now I am facing an issue that mailboxes residing on exchange 2003 can send email to mailboxes residing on exchange 2000 but users of exchange 2000 are not able to send the email to users of exchange 2003 server.
Users of exchange 2000 are getting the following NDR.
