Feature update, Admin impact



Microsoft Teams control messages are system-generated artifacts that contain information about actions taken in Teams - for example, adding or removing a user from a chat. These messages show up on the Teams client as system messages. Ex. User A added User B to the chat and shared all chat history. More information on these types of messages can be found here.
Until now, control messages were not included in the supported types of messages for retention policies for Teams (user chats, standard channels, shared channels, and private channel user messages).
We are pleased to announce an improvement to add support for retention and deletion of some types of Teams control messages using retention policies for Teams ("Phase 1"). Phase 1 includes support for control messages generated while adding or removing a member to a chat or Team, within Teams chats and Teams channels locations.
A separate communication will be shared for Phase 2.
[When this will happen:]
Phase 1 will begin rolling out in late March and will be complete in April.
