Accept and Decline button missing in thunderbird when receiving an invitation

Question

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?

Answer 1

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.

Answer 2

According to multiple threads I've found, Google cal does not support "Accept" or "Reject" somehow. http://forums.mozillazine.org/viewtopic.php?f=46&t=1826045

The solution was to set the "Automatically add invitations to my calendar" option, but it doesn't say whether on gmail or in lightning.

Just found a solution for me (not-a-google-calendar) - the calendar has to be associated with the email! http://web.archiveorange.com/archive/v/fdCyh9sjQ8kzJuM5rPM4

The "display attachments inline" option seems to be irrelevant in my versions - TB 16.0.1 , Lightning 1.8

Answer 3

Here is my work-around using Thunderbird 17.0.4, Lightning 1.9.1, and Provider 0.18. Double click on the invite so it is in its own tab. Right click on the email invite and a sub-menu appears. Select 'Convert to' and then a smaller sub menu window appears with "Google task", "Event", or "Task".

Select "Event" and it will place the details of the invite as a new appointment in your Google Calendar. The click ok.
