In Outlook 2010 I'm getting a lot of messages store in "Stuff To Keep Awhile" and have repeatedly checked the option to delete files from that folder that are older than 12 months, but it refuses to do so.

My mail comes through the Outlook that used to be Hotmail and of course I'm using the Hotmail Connector. I suspected the problem was that Hot Outlook was not deleting old files so I started checking there. Could not find anything to directly control that, but did set it to follow what other email apps said it should do. That hasn't worked either.

Someone please tell me how to delete those old files.
