We are building our environement to have the capability of providing email as a service. In short, the idea is that we will be having only one Domain in AD, but different OUs for different companies. Once this is created, we can create different Exchange DB related to different companies as per their domain. also, we may need to add a webserver that can handle email hosting as customer interface. i would like to add that above structure is all hosted in Virtual Environement.
Is it the right way to provide email as a service?
