I asked about this a few weeks ago and got no response, but the problem has
cropped up again and so I'll try asking the question again: I have a
recurring problem where the built-in junk email filter in Outlook just stops
working. This is the filter that requires no setup by the user and filters
out the obvious junk (though I think you can set the level to low, medium,
or high or something like that). Occasionally, it stops working and all the
junk email about debt relief, male enlargement, etc., etc., etc., just
starts landing in my Inbox instead of the Junk EMail folder. In each case,
I've made no configuration changes to Outlook. It just starts happening.
What I've found is that within two or three days the filters start working
again and most junk email starts going back...
