We are using Outlook 2007 with Exchange server. We have a user who has been
moving his emails off of the Exchange server to some folders he created or by
Auto Archive feature in Outlook 2007. He basically drag and drop the emails
from his Exchange server Inbox to his folders on the left side. The question
is, where are all of these folders full of emails located on the local
computer? At first I thought it must have been the Auto Archive feature that
kicks in every 14 days and created those folders for him to be able to drag
and drop, but when I check the following location the archive.pst file size
is very small.

C:\Documents and Settings\%your username%\Local Settings\Application
Data\Microsoft\Outlook\

The total folders of emails must be about 1 to 2GB in file size. Where else
on the local machine could Outlook had put it?

Any help is much appreciated.
