Difference between Chat and Contact
There are two main divisions in the MS Teams Chat section, namely Chat and Contacts. The Chat stores all the group and individual conversations’ history (internal and external). On the other hand, Contacts help you to organize your contacts to facilitate your daily communication among your peers.
It is an easy and straightforward way of having chats in one place, organized chronologically, and instantly retrievable by search.
Go to Chat tab > click on the Chat arrow pointing down > select “Chat” or “Contacts”.
