How to see audit trial for private 1-1 messages within Teams?

[Ashwin_Malhotra]

We have hybrid mode of exchange at the moment i.e. sync's on premise and Exchange is online.

I am looking to find an answer on how we can see all private 1-1 conversations done by users for audit purposes?

I know we can set user mailboxes etc but that is only possible with exchange online not with hybrid model I guess. A

Seeking advise on how to solve this problem.

@Ashwin_Malhotra For hybrid users the Teams 1-2-1 chat,  Private channel chats and private meetings are stored in a shadow Exchange online mailbox so the content is searchable via eDiscovery. See this Microsoft article Search for Teams chat data for on-premises users - Microsoft 365 Compliance | Microsoft Docs.

Also if you want have a deep dive into where content is stored in Teams I have just written a blog on it Microsoft Teams - Where is my data stored? - Nikki Chapple
