Please note that even if all of your conversations were legitimate interactions with friends, our Inbox message service is not a chat client and should not be treated as such. As a recommended alternative, we suggest that you check out the Facebook Chat feature, which allows you to exchange real-time messages with your confirmed Facebook friends.
To start using Facebook Chat, click the Chat icon in the bottom right corner of any Facebook page, and choose the "Go Online" option. You can start a conversation with any confirmed Facebook friend by clicking on their name in the "Online Friends" list. Once you send a message, your friend will receive an alert at the bottom of their screen, and they can reply by typing in the conversation box provided.
