Unread emails

[minxca]

Hi,

I have few users that their mailboxes are fillup with Not Read notification like below:
Your message

To: other user
Cc: other user too
Subject: RE: Scanner

I'm guessing it happened when outlook archive his/her old emails. I try to simulate the problem by sending few emails and told them not to read/open it and the next day I archive my Sent Items I don't get those messages.

Any idea?

Thanks,
Winoto
