Conversations, chat, and file sharing

For Students Last updated: 06. 09. 2026

Conversations are a central part of MS Teams. They give every team a shared discussion that is saved and can be searched later. Conversations record messages, file sharing, and links to video calls.

With an @ mention you can alert an individual, a channel, or the whole team. The person mentioned receives a notification. Users can like messages, react to them, or add emojis and animated GIFs.
