Preservation
Teams retention policies support: Preservation: Keep Teams data for a specified duration and then do nothing Preservation and then delete: Keep Teams data for a specified duration and then delete ...
Where did you copy that from? IMHO it's not very clear and even misleading. Yes, no items will be removed automatically if there is no retention policy in place. And yes, it's actually hard to delete stuff as the TeamChats folder is not exposed in clients. But if the user knows what he's doing, he can certainly delete messages from the folder. So if you need to ensure chat data is kept immutably for some duration, you need the policy.
TonyRedmond just in case.
VasilMichev Thanks, got it from here: https://docs.microsoft.com/en-us/microsoftteams/retention-policies and in the FAQ section.
I left feedback on that article to make it a bit more clear btw.
