restore default autoarchive folder settings in outlook
 

I'm new to Outlook and a message came up "do I want to Autoarchive?" Rather
than just say "yes", I changed the folder details to "My Documents". When I
went to open it Office "said" "opening this could damage your system!"
Q1: Can I safely delete the "files" in My Documents that originated from
Autoarchive?
Q2: How do I restore the default folder/file? It looked a bit like this...
C:documents\settings\myname\localsettings\applicat iondata\microsoft\outlookarchive.pst
I took very approx. notes of that, and that does not work!
Help?
