Every time someone reacts to a message in a team chat or channel conversation, Teams captures an audit record and sends it to the Office 365 audit log. The Teams reactions audit records are an interesting source of information.

Microsoft will soon make an update available for Purview Premium eDiscovery to reveal Teams reactions to chats and channel conversations when investigators review the results of searches. The information comes from Teams rather than the compliance records stored in Exchange Online. The new feature isn’t coming to Standard eDiscovery.
Microsoft is rolling out new activity feed controls for notifications posted by apps and when people use reactions to respond to messages. The idea is to make the activity feed less distracting for busy users. The interesting technical issue is how to deal with notifications created by the many hundreds of Teams-enabled apps available today.
