I am using the Provider for Google Calendar add on to add my Google calendars into the Lightning calendar add on for Thunderbird. I am able to setup reminders for calendar events that I create, but if someone invites me to an event I am not able to add a reminder. Does anybody know how to do this? I can add the reminder on the web version of Google calendar, but that setting doesn't sync to Thunderbird.
That appears to be a bug in Thunderbird: 799505 -No reminders for events organized by someone else
There is a related bug report / feature request open since August 2008: 451380 -Events from accepted invitations cannot be edited or updated locally
