I have a client using outlook in an exchange enviroment.
He tells me that he changed the view of his reading pane in Outlook 2003 and
when he did a lot of his email came up missing.
I have looked in his client and in fact all mail between 9/21/07  and
2/24/07 is in fact missing. (7 months worth of mail)
We have searched all his folders and it is not there.
We have opened every PST file on his system (archive folders) and it is not
there.
I opened his OST file and it is not there.
Exchange retention is set at 30 days and when I go to tools/ recover deleted
items, the items are  not in there either.

Anyone have any ideas?
