Add external messaging participants to your Yammer conversations

Sometimes you need to communicate with outside partners, suppliers, or customers. You can add external participants to conversations in Yammer so that you can work with the people you need, even if they aren't in your Yammer network. For example, you can add external participants to a discussion or use instant messaging to quickly get a response. External participants can view and download files that have been uploaded to the conversation, upload files, and they can view notes. You'll be able to see when a conversation includes an external participant, and you can remove an external participant when you need to.
