Update Task After Assignment
Enable a function that permits the creator and assignor of a task can edit it AFTER it has been assigned to someone else. Assignors should be able to "manage" the expectations of tasks they assign.
When we have a mail in task , it should automatically update the recent mail for that specific conversation if replied or any revert receive
I would also really like this functionality.
You should be able to do this, in Shared Tasks click on the Task and edit. You may need to change your permission setting but it should work.
