Hi Hauswirth1,

Here's a great resource to show you how to manage your calendar alerts: Keep track of events in Calendar on iPhone - Apple Support

If this doesn't help, please provide some additional details about your issue. Be sure to omit any personal details when providing context.

Take care.

Hauswirth1,

We'd need additional information in order to assist you. We'd be unable to speculate as to why you're receiving a message without more context.

For example, is this an iCloud calendar? What the specific word for word message you receive? Do you see this if you check your calendar via browser as well?

Alternatively, reach out to Apple directly for assistance here:

Take care.

Hi Hauswirth1,

This seems like unexpected behavior if you are not attempting to edit or undo your Calendar event when this message appears.

For more help with finding a solution, please contact Apple Support. 

All the best!
