Previously, there were two different room suggestion types based on a company’s Google Calendar settings. The first option lists frequently used rooms for you to pick from, while the second uses the structured meeting rooms feature to suggest rooms based on meeting attendees’ self-selected working location. Note that structured meeting rooms refer to rooms that are assigned to specific buildings, with meeting hardware and capacity information. Use this article in our Help Center to learn more about structured meeting rooms.
To better optimize meeting rooms and foster greater collaboration, especially in a hybrid work environment, Google are combining the two options in an updated structured meeting room setting. The working location set by a user is taken into account for all room suggestions, and in cases where location data is unavailable, proposed meeting rooms will be based on frequently used rooms.
