3 domain names onto 1 domain

[OFFYM]

My company has 3 offices

1 in UK (company.com)
1 in Miami (company-mia.com)
1 in Sydney (company-syd.com)

They are all connected via VPN tunnel and connected as 3 seperate forests through 2003 native mode.

the trusts are setup like the following........

company-mia.com <---> company.com <---> company-syd.com

each office has it's own exchange 2007 server.

I would like to keep the exchange servers working locally in there respective countries but i would like to have the entire global company to use company.com as the primary email address.

can anyone provide information on how i can acheive this goal??

many thanks

Make each forest a sub domain of a parent domain.

the company would like to keep the current tree/forest structure in place.

all three forests are root domains and would require demoting and promoting as sub domains, which would require alot of work.

as the current structure is in place, is there any way that exchange can be configured the preferred way rather than your original suggestion?
