Question
How to assign the "Complete Task" to a specific user
We have a lot of deleted users in our system, so we have many "tasks to be completed" assigned to users that no more exists (deleted users).
I would give to a particular user the ability to
1) execute the "Complete Task" action (the function run by clicking on the button "Complate task" in the work item details mask).
2) Reassign task.
3) Delete task.
Do anyone knows how to grant these action to a user?
