>When I click on Marked Messages it says 48 marked messages. What kind of clean up can I do?

I don't think we talk about the same thing. Could you go in your Account setup, in PUTM, and in Agent. In there, you'll find the list of 50 marked threads you have marked. You may remove the old ones. I will however enhance that part as well such as we did this morning for the Thread Filtering.
