An error occurred when writing to the calendar <calName> / MODIFICATION_FAILED

more options

When trying to delete a recurring event from a user-owned calendar (not Google, not network ical) I get the message "An error occurred when writing to the calendar Susan's Calendar / Error code: MODIFICATION_FAILED"

In the error console I get the following 2 lines:

There has been an error reading data for calendar: Susan's Calendar. However, this error is believed to be minor, so the program calCalendarManager.js:969:13 will attempt to continue. Error code: 0x80004005. Description: ID is null for deleteItem

An error occured when writing to the calendar Susan's Calendar! Error code: MODIFICATION_FAILED. Description: calCalendarManager.js:966

Why am I getting this error and how do I delete this event?

I've had this kind of error before, the only solution for me was to completely remove the calendar and reinstall it.

In my case I also had to export all events then delete the event from the exported file, then create the calendar again by importing the cleaned filed..
