Guests you invited can receive your messages via email until they join. They can reply to your emails and have their messages appear in the conversation stream. Guest indicators or labels are visible to team conversations and lists. This will help members of the team to avoid sharing confidential information and messages.

Members of a team will see the guest indicator on top, just below the team's name. The Message compose box will show a notification that messages you will send will also be visible to the guest(s) present on the team conversation.

On a team's list, a label appears next to the name of a guest.
