Hello aidan_w92,


This is probably a junk calendar.


Go to Settings > Calendar > Accounts and delete the calendar subscriptions that you do not recognize. (Note that the name may not include the wording you see in the error message.)


If you don't see any subscription or suspicious account:


  • Open the Calendar app.
  • At the bottom of the screen, tap Calendars.
  • Look for a calendar that you do not recognize. Tap the More Information button “i" next to this calendar, then scroll down and tap Delete Calendar.
