We have a single Exchange 2007 server running that is the mail server for two companies. Originally company A and company B fell under the same umbrella so sharing the global address book was not an issue. However, recently company B has been acquired by company C (which has no affiliation to company A).
We would like to keep company A and company B on the same E2007 server but would like to make it so that they do not share the same global address book. In other words, company A distribution groups, users and contacts would be listed in GAL A and company B distribution groups, users and contact would be listed in GAL B
Is there a way to make this sort of change to an existing E2007 environment?
