Infrastructure Requirements for Unity Deployment

Unity uses AD when deployed in the Exchange messaging environment. The corporate directory administrator must understand the implications of this before proceeding with actual deployment. Table G-3 includes the questions to ask the corporate directory administrator to ensure that the customer understands the infrastructure requirements to deploy Unity.

No.
