I have a complicated question and I am hoping someone my be able to start me in the correct direction.
I have two companies each with their own Domains. You can call one the parent company and one the child company. The parent is running on exchange right now and that is the bulk of the company employees. The child is small and is as far as the public is concerned a seperate company. Up to now I have kept them completely seperate, outsourcing the email function for the child. These individuals are moving into our building and I want to include them in the exchange system. They will need to keep there seperate domain as far as the outside world is concerned but participate like everyone else on the inside.
I could use any advise here. I am in need of the issues I am going to run into and possible resources to complete the project.
I appreciate the help.
