Description of the update for Outlook 2007: June 9, 2009

This update fixes the following issues:

• In Outlook 2007, you open a meeting request in the calendar. If you edit the meeting request and then click Save, a dialog box appears. When you click Don't save but keep the meeting open in the dialog box, the changes that you made do not appear in the meeting request.
• In Outlook 2007, you open a meeting request in the calendar. When you click Cancel Meeting and then click Save, a dialog box appears. When you click Don't save but keep the cancellation open in the dialog box, and then close the dialog box instead of clicking OK or Cancel, the meeting request closes unexpectedly. Additionally, the meeting request is removed from the calendar and Outlook does not send a cancellation notice.

Update information

This update includes changes to Outlook 2007 that were introduced in the February 2009 cumulative update. These changes include performance, calendar, security, and reliability improvements.

However, if you did not install the February 2009 cumulative update, 2007 Microsoft Office Service Pack 2, or the April 2009 cumulative update before you install the update in this article, the initial startup of Outlook may be slow. This is because Outlook must update internal data structures in .pst or .ost files that are used in performance optimizations. During this internal data structure update, you see the following dialog box and you must wait for the update to finish before you can use Outlook.



This is a one-time occurrence that affects only the initial startup.
