If you are getting this MODIFICATION_FAILED error code while editing your calendar using thunderbird, it is because you should instead edit your calendar by using it with Google calendar. 

You can use Google calendar with both thunderbird and lightning applications.

And if you are using Google calendar and getting this error, then you have subscribed to read-only iCalendar feed provided by Google calendar.

Go to the Google calendar help button and get access to CalDAV. This is the best tip that is going to help you out and it takes only 2 to 3 minutes to setup.
