The Extremely Useful Meeting Follow Response

The Follow response is a new option for people invited to a meeting to indicate that they can’t attend but are interested in what happens. Replying with a Follow response means that the user gains access to the meeting artifacts (like the chat and recap). It also means that the allotted time is not blocked in their calendar. The feature will be most valuable to people who have heavily-used calendars.
