i am trying to send emails from my old exchange 2003 box to a new exchange 2003 box. the old exchange is on a different forest than the new domain. is there a way to have the old exchange 2003 box deliver to current mailboxes on the old exchange 2003, then send all the emails to the new exchange 2003 box?

Are you trying to move mailboxes from old Exchange server to new one?

Most easy method would be, to ask users to take a PST backup of there mailboxes from outlook and then use it with there new mailbox.

If now, please provide more details.

no, i know how to move my mailboxes. i want to have emails sent to my new exchange box AS WELL AS my old exchange box. i want to do this so mail flow isn't interupted to the old exchange box as people are brought to the new box.

"do they bost host the same smtp domain?"

not sure what you mean. hopefully this helps. the old box is in a domain - lets call it domaina, and the new box is in a domain called domainb. domaina and domainb are on seperate forest. so mailboxes on the old box are, for instance,  user@domaina.com and mailboxes on the new box are , user@domainb.com. Does that help explain it?

yes it does

on your old exchange you will need to create for usera@domaina.com a contact user usera@domainb.com
then go to the user settings in ADUC and forward emails from usera@domaina.com to the contact who's email address is usera@domainb.com. if you want you can set the delivery option to both

finally on your old exchange create an SMTP connector with address space @domainb.com and cost 1 let it use a smart host the ip of exchange new

i tried making a contact but here is the problem. whoever originally setup the old domain did a horrible job naming it. so the domain name is domaina.domaina.com. so machines on the domain look like machine@domaina.domaina.com. our email address is user@domainb.com, so to avoid looking like spam, the people that take care of my dns set something up so that email coming from my old exchange box ( exchange@domaina.domaina.com ) would look like exchange@domainb.com. so when i tried to create a contact ( myname@domainb.com ) my exchange box has an error - the name exists. so i tried myname2@domainb.com. but that will simiply forward email to the same exchange box, different user name. so when i setup the new contact i tried, when i was selecting the recipient, changing locations to the new domain. then i choose a contact on the new domain, but when i go to apply the changes i get this error.

A constraint violation occurred.

I'm at a loss how this is going to work?

well another option would be to create another accepted domain and alias on your new exchange something like @dummy.local

then create all the contacts in forest old @dummy.local
