Google has implemented a change to Calendar designed to help avoid overlaps in meeting times. Rooms will no longer accept two Calendar events that overlap in time.

Previously, someone with manage permissions for a room could successfully create an event on the calendar for that room, even if it contained another event for that same time period. Now, if the room has already accepted another meeting, it will decline any new meeting created at the same time directly on the room’s calendar.

Details about this change are available in this G Suite Update article.

A new scheduling feature similar to Boomerang is available as well. Google added a convenient feature to Gmail that allows you to schedule any email to be sent at a later date and time. This feature is available on Android, iOS and Gmail on the web.
Just write your email as you normally would, then schedule it to be sent at a more appropriate date or time. It provides greater control, so you can shift your work time to whatever is most convenient for you and your recipients. Additionally, it’s even easier to collaborate globally—allowing you to work across time-zones while still respecting everyone’s digital well-being.
