Multiple Domains

[mrjhat10]

I have an existing Exchange 5.5 system. It is currently
setup for users to receive email @domainA.com. Whenever I
create a new user, they are automatically granted that
SMTP address username@domainA.com
I want all my users that currently exist to start
recieving email to both username@domainA.com and
username@domainB.com
I have found several documents, but none seem to apply to
specifically what I want to do.

Any help would be greatly appreciated
Thanks.

You will need the MX record for domainb.com to point to the same place as your domaina.com.
Then in Exchange set your internet mail connector routing tab to accept domainb.com inbound.
When you set up new mailboxes you will have to manually add the second email address (I think.)
To add an extra email address to existing mailboxes I would get Exchange to do a directory export to a csv file, then edit the csv file to have an extra column - 'Secondary-Proxy-Addresses', then use the same export using the same csv file. If you now open the csv file in Excel you can do some funky stuff to add an extra email address in to the Secondary-Proxy-Addresses field. Then import this back into Exchange. There is a slight risk that the csv file doesn't have enough key fields or that you accidentally change the value of a field that you didn't want to. So if its a small organisation you may want to add the extra email address manually, or read up on import/export.

Hope this helps
