Prevent users from deleting chat in private chat

[Ry3018]

As a admin, I would like to prevent users from deleting messages in their private Chat (not in Teams channel). I'd like to prevent users from deleting their own chat messages sent for tracking/verification purposes. 

What I have done so far

In Teams Admin Center, I turned off the following:

- Owners can delete sent messages

- Delete sent messages

- Delete chat

- Edit sent messages

It seems that settings were not yet reflected or is this only for Teams chat channels?

The portal settings do not affect personal chats, and there is no direct way to prevent deleting/editing messages therein. You can however use features such as retention policies to ensure that a copy of the message will be preserved immutably, or "communication compliance" to monitor conversations.

After few hours I checked back and it looks like the settings I modified in Teams Admin are now reflected. Users can no longer delete their sent messages either in Teams channel or private chat. Exactly what I was looking for.

Hopefully, they would also include a feature to see edit history in chat.

Interesting, I always thought those only apply to channel messages. Good to know, and glad you solved your issue.
