Can't dismiss Google Calendar reminders

Question

I'm using Thunderbird with Lightning and can't dismiss Google Calendar reminders. I click on dismiss and nothing happens.

Calendar is not read-only.

I've got this kind of errors in "Error Console"

[calGoogleCalendar] Modifying item xxxxxx failed:2147500037: {
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "forbidden",
    "message": "Forbidden"
   }
  ],
  "code": 403,
  "message": "Forbidden"
 }
}

There is a similar issue reported in another question. There are a couple of things there you may want to try.

• Ignore reminders for that calendar (if it is an option for you)
• Clear the cached data if your issue is about a Exchange calendar
