Accept and Decline button missing in thunderbird when receiving an invitation

eventsgoogle-calendarlightningthunderbird

I'm using Thunderbird 12.0.1 with the following add-ons for the calendar:

  • Lightning 1.4
  • Provider for Google calendar 0.9

I'm working with Ubuntu 12.04

When I receive an event invitation from Outlook or Gmail, the mail is correctly identified by Thunderbird (I have the message "this message contains an invitation to an event"). In the pretty little box in the mail (the one which contains all the details), there is no "Accept" or "Decline" button.

I found on the Lightning forum that this bug was fixed in Lightning V.1.0b2.

So, why am I still experiencing this bug?

Best Answer

I use a Google Calendar with Thunderbird/Lightning and I have always been able to Accept invitations through Thunderbird.

I recently lost the Accept/Decline buttons and just figured out the problem. I had recently added a shared iCloud calendar, and the new calendar was automatically associated with the same email address as the Google calendar.

All I had to do is set the iCloud calendar to not be associated with my email address, and my Accept/Decline buttons came back.
