Integrate 2 Exchange servers in different AD domains 1

[engjohn]

I have a project to install a 07 exchange server in a company.
Everything was going just fine until they told me today that the Michigan office already has an exchange server. The Michigan office is on a separate AD domain with no VPN.
Everyone currently uses POP3 for mail. The michigan office is using exchange as the data store for the POP3 email.

So, is there a way to utilize this existing exchange server now that corporate is getting a new 07 server.
They will not want to separate the email domain (ie user@la.company.com and user@mi.company.com)...

With different domains, can I share a email domain across 2 exchange servers, and can they share resources?

Yes, you can set this up, but one of the servers will need to be the main delivery location and it will route any non-local mail on to the other server. There is no need for trust between the domains: this could be a purely SMTP relationship.

If you want to share resources like public folders, calendars and other internal Exchange things, that's a whole different story, and you'd probably want to find a way to put both servers in the same Exchange organization (and, by extension, the same domain).

If you want both offices to share tight integration, maybe you should consider having the Exchange server exist in the LA site, but be a member of the MI domain, and create mailboxes for all LA users in their AD. Or...consider going with a hosted Exchange solution like Microsoft's BPOS, so that both sites could run on Exchange 2010 and share all resources in common without the complications of trust between your existing AD sites...
