So companyB acquires companyA and will eventually all be under domain of companyB.  Down the road, the goal is to have an exchange environment with users from both companies on the B domain.

Right now, we have A users able to send and receive on B domain through combination of AD contacts in domain B and public address of A in B spf record so that part works.

What we are trying to do now is have the ability to view calendars (free/busy) and GAL from B on the A domain.  I have looked around a bit and found that it doesn't seem to be that easy.  A is 2003 and B is 2007 (later we'll merge both to 2010).  I understand the first part is to get the ipsec tunnel working and forest trust setup between A and B.  The exchange part could be an issue.  I've found a posting suggesting to use microsoft inter-org utility but it would only work for public folders; doesn't solve the GAL issue.  Has anyone had to do this before?  If I were to use it for free/busy, would the 2007 B server need a pf store (for 2003 compatibility so our server can see it)?

Assume that Company A under Domain A while company B under Domain B.

1. Make sure that both DNS server able to resolve each others.
2. You need establish trust between 2 domains.

So share the GAL/Free busy, you must create a "Linked Mailbox" for User at Company B.

As I said, I'm already aware about the first parts to get the network and domains talking to each other.  As far as that article goes, it applies to Exchange 2010 SP2; only 2003 and 2007 are variables here.  Moving to 2010 is another project for another day; management hasn't given us a lot of time to get this first part going.

we ended up using quest collaboration services which did what we wanted; seems there is no native way of doing this
