The Project Server 2007 External Connector is an optional product for the EPM Solution that permits non-employees such as partners to collaborate on projects.

To allow your business partners or customers to access your network, there are two licensing options:

·         Acquire Windows CALs for each of your external users.

·         Acquire External Connector (EC) licenses for each server that will be accessed by your external users.

An external user is a person who is not an employee, or similar personnel of the company or its affiliates, and is not someone to whom you provide hosted services using the server software.
