Event notification for events not on the calendar

Hi Rich Wingerter,

If you have multiple emails accounts on your iPhone, the calendar events may be related to one of those accounts. To check, go to Settings > Calendar > Accounts. You will see your lists of accounts and you will see Calendars listed under each one that has it enabled. Make sure the events are related to one of those accounts.

For more information about setting up and using multiple calendars, review still article: Set up multiple calendars on iPhone.

If the information above doesn't help, we recommend contacting Apple Support here: Get Support. They will be able to further assist you.

Take care.
