I had the same problem. I have Office on automatic updates, so I don't really
notice when they happen -- therefore, no idea if the problem happened after
updates. It's happened 4 times over the last 6 weeks or so. Each time, doing
a Repair (Control Panel>Add/Remove Programs>Change, then choose Repair) fixed
the problem temporarily.
Interestingly, I tried the instructions that were given on fixing the rule
file (
http://www.outlook-tips.net/howto/fix_junk.htm), which involved deleted
the rule file, and there was no rule file! And, contrary to what was in those
instructions, closing and opening Outlook obviously didn't create one --
since the problem lasted for several days until I repaired Office.
Mine is now working, after the 4th repair and I'm trying to pay attention to
what I do -- and what happens automatically -- to see if I can catch anything
when it happens again.
By the way, I'm also getting e-mail inexplicably put into my Deleted Items
folder. I haven't figured out why that happens but I just check it every day.
Sigh!
