To Reject a Task

Providing you have been assigned the proper user authority to reject tasks, you can reject a work task that is in your Inbox, Rejected, or Forthcoming Work Exchange folder.

Follow these steps to reject a task from a Work Exchange folder.

Open the Work Exchange folder that lists the task that you want to reject. All relevant tasks appear.
Select the task from the list by checking the box to the left of the task name.

Tip: You can select multiple tasks by selecting more than one check box from the tasks in the list.
From the Actions menu, select Reject selected.

The Reject Task dialog appears, for example:
Enter the reason for the rejection in the box provided, and then click Reject task. The rejected task is stopped and returned to the workflow owner for reassignment. You may also view a list of your rejected tasks, from the Work Exchange - Rejected folder.
Repeat Steps 2 to 4 for each task that you want to reject.
