Check if that is one of the accounts you are syncing with the Calendar at Settings > Apps > Calendar > Accounts, and under the account name, you will see if it is syncing that account to your Calendar. For me, the only account I use for syncing the Calendar (and Contacts) is the iCloud account listed there. The other accounts just show Mail, so those are not using any Calendar sync.

  • Are these Event Invitations with no option to delete?
  • Do you have a Hotmail, Outlook, or Microsoft Exchange email account?


Microsoft has had problems with spam invitations infiltrating their email servers and if you choose to sync the Calendar of that email, you will see them show up in your Calendar app. You can quit syncing the calendar of that email address and they will immediately be removed from your Calendar app. This happens a couple times each year with those Microsoft accounts.
