Find more information about a teammate in Teams
If you hover over a teammate’s profile picture, you’ll see a profile card containing their details. Start a chat, call, or send an email to someone from their profile card.
To ask more specific questions about someone in your org, use Who. Who is a bot whose sole purpose is finding info about the people you work with.
Type /who into the command box at the top of Teams to start asking questions such as "Who did I email yesterday about data storage?" or "Who is John Smith?"
Asking a question directs you to a one-on-one chat with Who, so feel free to view your answer and ask follow-up questions there.
