One additional thing to remember is that Outlook 2003 and 2007 use a
different method for indexing the mailbox which could account for some of
the issue. Using a single version of Outlook with the mailbox would
probably clear up the issue after deleting both mailbox contents and
allowing Exchange to rebuild each one.

I have a user who uses two computers at different times through out the day.
One has Outlook 2003 and the other 2007. Both are set up to use Cached
Exchange Mode accessing an Exchange 2003 server.. When the user views email
on one computer, then goes to the other computer and opens up Outlook, some
of the emails are not there and vice versa. My first thought was that
there's
not a copy being left on the server. However, I do not see a setting for
this
like you have on a pop3 setup for instance. I know that more detailed info
will probably be needed to get an answer here. Just let me know and I will
supply any additional details. Any help on this would be greatly
appreciated.

Thanks
