What to do if someone has access to your calendar

If someone has added events to your calendar without permission, take these steps:

1. Delete unwanted events individually. Open your calendar and remove any events you do not recognize.
2. Review calendar sharing settings. Open your calendar settings, review who has access, and remove any person or account you do not recognize.
3. Check for suspicious calendar subscriptions. Look for subscribed calendars you do not recognize and unsubscribe from or remove them.
4. Secure your email account. Change your email password and enable two-factor authentication if you suspect someone accessed your account.

The exact steps may vary depending on whether you use Apple Calendar, Google Calendar, Outlook, or another service, and whether you use an iPhone or Android device.
