In Exchange 2010 server, we have setup a policy under "Default Archive and Retention Policy" as all messages under "Inbox", "Sent Items" and "Deleted Items" will be Permanently Delete after X months.
However, one of our client found that some of the email messages was still found under his "Deleted Items". All other email messages under her outlook client (2010) were successfully deleted according to the policy.
Is there any reason for this exception?
Thank you
