Events appear after being deleted

Problem

Events reappearing after being deleted.

Environment

  • Google Calendar

Solution

  1. Check the Drive log events for third party interactions with Google Calendar permissions.
  2. Go to the Admin console > Reporting > Audit an investigation > Calendar log events > Add filter > Event title > Drop down menu > Contains.
  3. Type the Event name and click Search.
  4. Locate the column called Event, there the Event created action appears.
  5. Click on the description >  API kind and User agent

Cause

Third party applications were interacting with the Google Calendar service, and it is highly probable they were recreating the events after being deleted
