Currently, when modifying a recurring event you can either delete all occurrences or the current occurrence. It would be nice to be able to delete the future events, but leave those that have already occurred unchanged.
Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.
I support this request. I need to delete a series of repeating future events but wish to retain those earlier events as a record in my calendar.
Is there any way to find out when this feature will be implemented?
@Аlex let me check with the Thunderbird team to see if this is on their roadmap
