Expected results:

The Task should have been stored in the new calendar. Both calendars (old and new one) are WebDAV calendars.

That error would seem to indicate a resource conflict, meaning a task with the same id is already present in the calendar you were trying to move it to. If you restart Thunderbird is there a duplicate task shown, one per each calendar? Can you duplicate this error with a new task, or a different existing task?

Sorry, but there is no duplicate task-entry, even after restart.
Both Calendars have different caldav-addresses at iCloud (Mac) on the same domain https://p01-caldav.icloud.com. The Login for both calendars is the same email an password combination.
Even when I try to switch calendars with completely new tasks, I get the same error.

Do events have the same issue, or does this only happen with tasks?

Comment 4

[tomsteg]

Good question, because it happens also with events. 
I stored a new event, opened it again, changed the calender, tried to store it and got the same error.
Afterwards the calender, I wanted to change to, has a warning symbol (!) beneath it at the left column. After manually syncing that calendar, the warning symbol disappears.

Thanks for reporting this issue! However, tt has already been reported before.
