Change phone number on a calendar event

Hi howardfromlafayette,

To resolve your issue with editing an event, you can complete the steps listed here: Create and edit events in Calendar on iPhone - Apple Support that are also listed below.

"Edit an event

You can change the time of an event and any of the other event details.

• Change the time: In Day view, touch and hold the event, then drag it to a new time, or adjust the grab points.
• Change event details: Tap the event, tap Edit near the top right, then in the event details, tap a setting to change it, or tap in a field to type new information."

Also, since you are pulling the event from the email, it will not allow you to edit their personal information, but you can add the new phone number in the notes field of the event and once saved, you can click on the number to call them from the event itself.

Best regards.

Hey howardfromlafayette,

As the event is being added via email, you may need to have the original creator of that event update the information.

For further assistance, we'd recommend contacting Apple Support here: Apple Support

Thanks!
