If you’re in an active Teams chat with one or more people, it can be a bit confusing when you try to reply to something that was said earlier in the chat. It’s scrolled off the screen, and people may have lost the context behind your latest chat entry. Teams now has a feature that allows you to reply to a specific chat entry and keep the context of what you’re responding to. Here’s how that works…

Please note… this only works for chats you’re having with individuals. It does not apply to conversations in a Teams channel.
