Outlook 2002: New Contacts & Events wont appear

[Phil H]

Hi;

I've been struggling to get Outlook 2002 to add new
contacts. They are created, but the names won't appear.
Or I get the error; Errors have been detected in the
file ....outlook.pst. Quit all mail-enabled applications
and then use the Inbox Repair Tool. I've run the SCANPST
program a few times, no errors.

Also when I try to add an event to the calendar, nothing
appears.

I have had these problems since Outlook 2000, which was
the main reason I upgraded to Office XP Pro. But it
hasn't solved the problem.

I've been trying to reduce the size of the .PST by
archiving and deleting files. I've also compacted it,
but is still over 500,000kb.

Your help is much appreciated,

Thanks,

Phil H
