Since I set auto-archive settings for Outlook I've been getting an error message when I try to open it in the morning. pst file in use. Outlook will finally open after I shut down the computer. It is an HP desktop and their solution is to turn off computer, unplug from the wall and hold down power button until a green light goes off, thus eliminating static build up. I turned the auto-archive off and eliminated the problem but I really need to auto-archive. Any ideas.
