Is it possible to chat / Instant Message with SmartCloud Engage members that are not in my organization?
To locate and chat with members outside your organization, you must first connect with them from the service. Invite the person you want to chat with to your network. Once that person accepts and you are connected, you can then discover and chat with them using the instant messaging client. See How do I add someone to my contact list?
Note: Guest accounts do not have access to the chat or instant messaging features.
