Important: To make sure invitations from your trusted connections are automatically added to your calendar, add their email to your contacts. Learn how to add a contact.

  1. On your computer, open Google Calendar.
  2. At the top right, click Settings and then Settings.
  3. On the left, under “General,” click Event settings and then Add invitations to my calendar.
  4. Select an option:
    • From everyone: All invitations are automatically added to your calendar.
    • Only if the sender is known: Events are automatically added to your calendar if the sender is in your contacts, part of your organization, or someone you previously interacted with.
      • If an event isn’t added to your calendar, you get an invitation email.
      • After you mark a sender as known or you interact with them, future invitations from that sender are automatically added to your calendar.
    • When I respond to the invitation in email: An event is added to your calendar only after you respond to the email notification.

Important: If you select Only if the sender is known, it might reveal to senders that they aren’t in your contacts.

Limit visibility for pending Calendar invitations

When you share your calendar, you can choose whether to show only the events that are visible on your calendar, or all events, including invitations from unknown senders or invitations that you haven’t responded to and aren't yet visible on your calendar. This option appears under “Add invitations to my calendar” when you select When I respond to the invitation in email or Only if the sender is known.

Important:

  • People who only have permission to find your availability can’t get event details. Learn about sharing permissions.
  • When you allow others to find your event invitations, they may be aware of events that are not added to your calendar yet. This is helpful if they manage incoming event invitations in your calendar.
  1. On your computer, open Google Calendar.
  2. At the top right, click Settings and then Settings.
  3. On the left, under “General,” click Event settings.
  4. Turn off Let others see all invitations if they have permission to view or edit my events.

Fix issues with invitations

If you mark a sender as known or interact with them, but invitations are still marked as "Unknown sender invitation," make sure your Google Account allows Google products to save contact info when you interact with people.

To automatically add future invitations from a sender to your calendar, you can manually add senders to your contacts.

If you still find spam events in your calendar on your Android device after you turn on Only if the sender is known, you may want to review which apps have access to your calendar.

Unmark a sender as known

If you accidentally click I know the sender, but don’t trust the contact:

  1. Go to contacts.google.com.
  2. At the top left, click Main menu and then Other contacts.
  3. To the right of the person’s contact info, click More actions More and then Delete and then Delete.

Tip: A contact shows up as an unknown sender if you blocked them from another Google product.
