Michael J --
Are you the project manager of this project? From your description, it
sounds like you are the PM. If so, you have made a huge mistake selecting
the completed tasks and clicking the Delete button. In doing so, this will
set a Delete Assignment Request back to your PM (I assume the PM is you) for
each deleted task. If the PM approves these Delete Assignment Requests. the
system will REMOVE YOU from the tasks in the Microsoft Project plan. This
is NOT what you want. Instead, the PM should Deny each of these Delete
Assignment Requests. He should then open the project in question, insert
the Publish column in any task View (such as the Gantt Chart view), set the
Publish value to No for each task, and then save and publish the project.
This will remove the tasks for that project from the My Tasks page for each
team member. Hope this helps.
