Our Insights:

If you currently have forced chat history off, you will need to actively enable Hangouts Chat in your Admin console regardless of your setting for opting in to the new service. This is because “room” conversations in Chat always retain Chat history, regardless of your settings, so it's important that you understand this before enabling the service.

• And please also note if both classic Hangouts and the new Hangouts Chat are enabled for an organizational unit (OU), the classic Hangouts history on or off settings are used in chats in which participants use a mix of classic and new Chat. If the history settings are different for chat participants of different OUs, the chat conversation can’t be created. Please review your chat history settings for both products.
