All settings for archive and auto-srchive are gone! It's like that function has been removed from my Outlook installation. I ran Office repair from the control panel/Programs and features, still have the problem. Running Windows 7 64bit with IE9 beta installed. Auto-archive ran last month, but its gone now.
PS- I ran Inbox repair tool on both files (outlook.pst and archive.pst) still don't have the archive function available.
