After installing Exchange 2007 to single forest Exchange 2003 domain, 2003 does not see 2007

Hello,

I installed Exchange 2007 to our single forest, single domain
enviroment with one Exchange 2003 server (Same server is also DC while
new one is not). Installation went smoothly and I did all the
preparations.

After server software is installed (Server 2003 R2 64-bit), you get
questionare about "Install updates" and then you can "Enable
communications" (Lifts traffic restrictions in TCP/IP protocol). I
never got change to press that button which would enable tcp/ip, so my
question is this:

Did this affect my new server somehow because Exchange 2007 can send
messages to persons in Exchange 2003 but 2003 cannot see nor send
mails to mailboxes in 2007. Exchange 2003 management tools also says
that "tracking database" is disabled in 2007.

Any hope I can make them see each other and communicate?

Thank you for your time and help!

1. Outlook 2003/Exchange 2003 clients cannot view calendars of Outlook 2007/Exchange 2007 users

2. Exchange 2003 migration to Exchange 2007 in a separate forest

I have an existing forest/domain that runs Exchange 2003. I created a
completely new forest and domain and installed a new Exchange 2007
organization. I am creating a forest trust to migrate the mailboxes from
Exchange 2003 over to Exchange 2007.

I plan to use the ADMT to migrate the user accounts. I have two basic
questions.

1.) what is the best way to migrate the Exchange mailboxes
2.) How to I have email forwarded over to mailboxes in the new Exchange
organization once I migrate the mailbox from 2003? In other words, email
will continue to be delivered to the Exchange 2003 organization until I can
get ALL of the mailboxes migrated over to the Exchange 2007 organization.
How do I forward those over to the mailboxes that have been migrated?
