If you use Teams you already know it provides chat capabilities.
You also know that chat messages are listed in historical order and you can reply only to the last message received.
Well, not anymore, you can now reply to a previous/older message.
This can comes handy as sometime you can not reply immediately to a specific message.
To reply to a previous message, just browse the chat history to locate the message and open the ellipsis for this message to choose Reply
This then will include this message in the typing zone where you can then reply to this specific message
