Find users chatting with external users in Teams

[Gurdev Singh]

Is there a way to determine which users are doing 1:1 or 1:Many chats with external users? We are after a report that shows only the user names, actual message content does not matter as long as we have the sender and the external recipient details.

Hello, you can use Content search in the M365 admin center under "Compliance".

Thanks Christian...Content search is not ideal given it exposes the entire conversation. It appears to be the only option though to get the report about external chat participants.
