Exchange 2003 Migration

We just purchased a company that is on Exchange 2003. We plan on configuring a two way trust. What is the best way to migrate their mailboxes to our Exchange servers  and have our Exchange Organization accept email for their domain but still have them log on using their domain credentials to their domain?

The best bet is to add their domain to your exchange server as an accepted domain (which version are you running and I can give you instructions)

Update the MX record so that it points to your exchange server and then setup shared name space so that any e-mails destined for this domain are forwarded to their exchange server.  Again if you let me know what version of Exchange you are running I can give you instructions.

Exchange 2003 Enterprise  Thanks  We do not want to use their Exchange server as we will at some point migrate all accounts into our domain. We want all emails coming into our exchange server

If you want them to use your Exchange server then they will need to login with credentials from your domain.

I would suggest setting up the shared name space as an interim until you can move them all over.

This would cause very little disruption.
