Prevent spam by adding invitations from known senders only to your calendar

To help keep your Google Calendar free from spam, you can now select an option to display events on your calendar only if they come from a sender you know. If you select this option, you still get email event invitations from unknown senders, but they appear on your calendar only after you accept.

Senders you know include:

• People in your same company domain (like @google.com)
• People in your contacts list
• People you’ve interacted with before

As before, you can also choose to have all invitations appear on your calendar, or only those you’ve accepted—letting you customize the display to best meet your needs. 

Additionally, admins can set the default reply option for their users in the Google Admin console. Note that end users can indicate their preference in their own Calendar settings.

• Admins: The default option is to show invitations from everyone, and this can be changed at the domain level. Visit the Help Center to learn more about automatically adding events to calendars. 

• End users: Users can see and change the default option in the Calendar settings. Visit the Help Center to learn more about managing your incoming invitations and notifications.

• Rapid Release and Scheduled Release domains: Gradual rollout (up to 15 days for feature visibility) starting on July 20, 2022
