How can I set up a single Exchange 2010 Forest in a dual AD domain environment.

We have existing, one US and one UK AD domain. We want to setup exchange so that all users have a ".com" email address in a single redundant exchange environment spanning both AD locations. Or do we have to create a new single AD domain first?

AFAIK you have to set accepted domain for your second one nothing els you need to do.

Hi Trobby,

Setup single forest and multiple domain is supported, you may refer the previous answered thread to understand better.

You need prep the both domain prior installation

For installation spanning to different site, you may refer to the illustration diagram to understand the concept.
