Issue that this hotfix package fixes

  • Consider the following scenario:
    • You have a computer that is running Office Outlook 2007.
    • You send an e-mail message that is Information Rights Management (IRM)-protected to a user who is running Office Outlook 2003.
    • That user reads the message. In this scenario, the icon of the read message is displayed incorrectly as a closed envelope in Office Outlook 2003.

      Note When the message is read in Office Outlook 2003, the subject of the message is displayed correctly in regular text (not-bold), and the unread count decreases as expected.
  • In Microsoft Office Outlook 2003, when a delegate sends a message that requires a read receipt on behalf of other users, the read receipt is returned only to the other users. The read receipt is not returned to the delegate.
