Processing message failed. Status: 800004005
I'm using Thunderbird 60.5.3 on Windows 10 with Lightning. I've added a FastMail calendar account using CalDav:

I signed up for a Docker birthday event:
Docker sent me a calendar event. I tried to accept the event in Thunderbird, and I selected my FastMail calendar. Thunderbird told me:
Processing message failed. Status: 800004005
I can manually add events to the calendar without any problem.

Is the event duplicated on another date?

No, Docker had just created the event, and it generated the invitation for me from scratch.
