As mentioned in MC233470 published on 23rd February. This recap is really a good feature that gives us to find all the content in one place (the meeting recording, transcript, and chat). These are automatically shared in the Chat tab and viewable in the Details tab.
But this update will not be enabled on channel meetings.
MS will be rolling this out by early March (previously end of January) and will be complete by early April (previously mid-February).
What exactly the new feature?
For each scheduled meeting, users will see an updated view on the calendar Details tab that utilizes existing meeting data as shown below image.
This is how the new feature looks like once it is rolled out.
