Multi Site Exchange 2007 with Active/Active DB? And conenction aware DB pointer?

I have done plenty of research and I think I am now more confused or at least over thinking what I am trying to achieve with Exchange 2007.

Here is my situation..

Presently we have two sites one in North America the other in Europe. Currently our Exchange 2007 server resides in North America. Users at our office in Europe, access mail over VPN tunnel to the server. The bandwidth in Europe is not up to the same levels that we have in place in North America, and we are trying to optimize utilization where ever possible.

I have taken on the IT role from a previous employee.  I have done several Exchange installs, but they were always just local and basic.

So my question is this:

If I install Exchange 2007(already purchased software years ago, but never used) at the Europe office, can I point the users in Europe to a local DB which would reduce much of the current exchange traffic(all EU users to NA) to simply server to server, and also reduce the current delay in emailing somebody sitting in the same office, because the email leaves euro office to server in North America and then back to euro user recipient?

Further to this, if the user is visiting North America and working at the NA office, his site link (IP) would point to local DB copy as oppose to requiring the user to go all the way to the EU server to get his email…possible?

Just lost now after reading for many hours if not days about replication (local and cluster) and now 2010 with DAG….would rather not have to upgrade to 2010 and be required to purchase two server licenses plus all new exchange CAL’s at this time.

But is this even possible? I guess it would be like a replicated or distributed DB in an active/active mode and then with connection aware DB pointer….??? Maybe with DFS?

Thanks in advance..

sergio,

You can only have one active copy of the database at a time.  That said you can have two databases, one for Europe and one for North America.

One thing to note if you purchased 2007 do you have software assurance?? If you do you qualify for new versions as part of your existing license agreement.

The improvements in 2010 with regards to replication and DAG are great.
