Accept or Reject an Assigned Task
Tip
When you accept or reject a task, Outlook deletes the task request
message from your Inbox. You can’t control this behavior to prevent
Outlook from deleting the message. However, Outlook keeps copies in your
Sent Items folder of task requests that you create.
Tip
When you reassign a task that someone has assigned to you
and that third person accepts the task, Outlook sends an acceptance
notice to you and to the task’s originator. The status update list then
includes the originator’s address and yours, so you receive status
updates along with the originator.
