Google Calendar can block an event organizer through the computer interface. Review the broader effects before using it: Google’s current guidance says the block also applies in services such as Chat, Drive, and Photos. This is more than hiding one calendar invitation.
Check the supported context
Use Calendar on a computer and open an event from the organizer you intend to block. Google says this workflow blocks other Google Accounts. It does not provide the same organizer-block operation for every non-Google address or subscribed secondary-calendar context.
Apply the deliberate block
Open the event’s More options menu, choose Block followed by the organizer’s name, and confirm. The selected event is automatically removed. Google’s guidance says other existing invitations can remain, so do not describe the operation as deleting every earlier event from that person.
Most importantly, blocking does not remove calendar access previously granted through sharing. Review those grants separately when the person should no longer view your schedule.
Verify the remaining relationships
Check the account’s blocklist and any relevant calendar sharing settings. Previous-event updates can still produce Gmail notifications under the documented conditions, so one block is not proof that all communication has stopped. Delegates and secondary calendars have additional restrictions in Google’s guidance. If you later unblock the person through the Google Account blocklist, previously blocked events are not automatically restored; new invitations may be needed. The completed action should identify the intended organizer and remaining access relationships, without promising that a Calendar block retracts earlier copies, removes all sharing, or prevents every possible interaction across every service.
