If we assume good network connectivity :-) and you have
the ability to create trusts between the domains/forests
then:
The Exchange server will have to exist in 1 of the
forests. You will need to create disabled mailbox
enabled user accounts in that forest for each of the
users in the other 2 forests. On the advanced Exchange
setting tab you will want to grant Associated External
Account access to the security principal in the
appropriate forest. You will also want to look into a
metadata type product. MS has a free version of MIIS
available for this scenario.

>I have three established networks that will be connected
using layer 3 switches in the next month. The company
does not want to combine the active directories together
for the three networks. They are currently using a
program called Mail Daemon to get e-mail. They want to
migrate to an Exchange server and have all three active
directories connect to that one Exchange Server. Is this
possible?
