SYMPTOMS
A delegate for another user's mailbox can read messages marked as Private using the Microsoft Exchange Client. This behavior does not occur when using the Microsoft Outlook client.



CAUSE
The Microsoft Outlook client is designed to filter messages marked as Private so that only the intended recipient can view the message through his or her Inbox. This filtering process prevents delegates from viewing the contents of private messages that were intended for the original recipient only. The Microsoft Exchange Client ignores this sensitivity property and displays the messages to the delegate, as well as to the original recipient.



WORKAROUND
To ensure privacy, have the delegate for the user's mailbox install and use the Outlook client only.
