I wanted to make you aware of an update for Outlook 2007 which offers improved performance. I’ve attached a brief description below, more information is available in KB933493.

 

Brief Description

This update fixes a problem in which a calendar item that is marked as private is opened if it is found by using the Search Desktop feature. The update also fixes performance issues that occur when you work with items in a large .pst file or .ost file.
