create mailboxes for child domains in One exchange 2003 database

hello guys,

Im currently have root domain called abc.com and have exchange 2003 SP2 setup in it. I also have setup one exchange 2003 database called Company1. I'm in the process of creating 3 different child domains for 3 different agencies within the same company agency1.abc.com, agency2.abc.com, agency3.abc.com. My question is will I be able to create a mailbox for 1 user in agency1, 1 user in agency2 and 1 user in agency3 in the same exchange 2003 database called company1? or do i need to create 3 different exchange databases, one per each child domain?

any feedback i would really appreciated. thank you

As long as you setup your exchange to handle mail for all 3 email domains, you should be able to host the mailboxes in any database available to the exchange. The main thing is to setup the correct sending policies to make sure the specified groups of users are sending out with the correct domain.

Here are a couple of links for setting up multiple domains in a single exchange environment for 2003
