Has anyone an idea why tasks do not disappear from the My Tasks list?
In our SharePoint environment many task lists exit for our users. Most users use their own My Tasks list to maintain the tasks assigned to them. When a task is marked as complete in the original task list or in My Tasks, the task is updated and disappears from the My Tasks list.
But sometimes tasks are deleted from the original task list and keep existing in the My Tasks list. Trying to mark that task as complete in the My Tasks list does not work.
Does anyone have an idea how I can re-sync these lists?
I already deleted the user profile and created it again, but that did not help.
