I ran scanpst on Outlook.pst and fixed the PST after three times of scanning
and fixing session.

I then started Outlook with /safe switch (I noticed the navigation pane was
off, the navigation buttons returned to default settings, etc), and let
Outlook run for a while. Then I shut down Outlook and ran scanpst on
Outlook.pst, same thing happened, scanpst detected errors in the PST and
offered to fix the errors. Ran scanpst three times (scanning and fixing) and
scanpst detected no error on the fourth scanning.

I do have Kaspersky Internet Security 2010 scanning incoming/outgoing emails
and so far I haven't seen any visible problem with Outlook. Could it be the
anti-virus engine? Isn't running Outlook in Safe Mode supposedly turn off
all the add-ins and such?

I have the following add-ins active in Outlook:
· COM Addin for Microsoft Office Outlook Connector
· Kaspersky Outlook Anti-Virus Addin
· MAPILab NNTP Add-in
· Office Genuine Advantage Add-in

Do you have any third party tool accessing the pst, eg a Desktop Search
Tool?

And if you start Outlook using the safe switch, then after shutting
down,
then running scanpst does it then find errors?

I have used scanpst from time to time to repair my Outlook.pst. I
usually
run it a few times on Outlook.pst until it reports that it finds no
error.
Then I start up Outlook that reads Outlook.pst and mounts it as my
Personal
Folder. Sometime later, I shut down Outlook and out of curiosity, I run
scanpst again on Outlook.pst. This time scanpst again reports that it
finds
problems and offers to fix it, I run it a few times on the PST until no
error is found. I start up Outlook again and the cycle repeats. So,
Outlook
2007 "corrupts" Outlook.pst every time it is accessing the PST?

Until now, Outlook 2007 has not yet failed to open Outlook.pst for me
and I
do back up Outlook.pst regularly but this worries me a little.
