If you need an answer or want to share an information, here we are explaining to you whether you should use the channel or the chat.
Think of your channel as a whiteboard inside your classroom where the information posted here will be visible by all and will stay.
Only start a conversation in your Teams channel if you think your post would benefit all users and this information should be easily found.
To start a new post, type your message in the box Start a new conversation. Click on reply if you want to answer or add information on a specific post.
Use the chat for day to day operational conversations. You can also use the chat to replace phone calls or direct messages when you need a quick answer from a limited group of people. You can create group and 1:1 chat conversations.
