How Activity logging works
Choose whether a chat's work becomes a summary in a pod's Activity.
The choice is for this chat
Turn on logging when you want this thread's work remembered in its pod. Nothing is posted when you choose. Not this thread keeps a shared-pod chat out of Activity. If an unselected 1:1 DM offers a pod, Not now keeps its personal-pod default; in a group DM it leaves the thread unlogged. You can change the choice later.
A summary when the chat goes quiet
Mosaic summarises a conversation after it goes quiet when Activity logging is on. The summary can include decisions, work done, work in progress and follow-ups. It is a summary of the chat, including earlier messages, not a copy of every reply.
Where it goes
A chat acting in a shared pod logs to that pod's Activity. An unassigned 1:1 direct message or a web chat acting across the whole organisation logs to your own personal pod. In Slack, you can choose a shared pod for a direct or group DM; a group DM can use only a pod everyone there may read. Not now keeps a 1:1 DM on its personal default and leaves a group DM unlogged. Activity readers can see the summary only where they have access.
Turn logging off
Use the chat's Activity logging control to choose Not this thread. Later messages stay out of Activity. A summary already published remains in its pod until someone removes it there.
