Microsoft has - rather quietly - released an preliminary update for Microsoft Outlook 2007 that will also be included in the soon to be coming Microsoft Office Service Pack 2. The Outlook 2007 update increases the performance and responsiveness of Microsoft's desktop email client noticeably. Four key areas are improved by the patch including startup, shutdown, general responsiveness and folder or view switches.
The general responsiveness of Outlook 2007 has been increased by reducing the I/O disk usage processes and UI response times. Startup has been improved by moving long operations from the initial startup phase, while shutdown time was decreased by making Outlook exit predictable. Finally the folder and view switching benefits from improved view rendering and folder switching routines.
The update is currently classified as a hotfix meaning that users will have to request it by providing their email address on a form at the Microsoft website. Users who do use Microsoft Outlook 2007 as their main email client will benefit from the update to a large extent. Startup time might be slower during first startup because of a one-time data structure upgrade. The performance gain during startup or shutdown should be noticeable afterwards however.
Microsoft has updated the Mailbox Storage Size Guidance to reflect the performance and responsiveness improvements when utilizing Cached Exchange Mode with respect to mailbox/OST sizes:
The service pack for Outlook 2007 contains additional improvements for components like the Calendar or Outlook search among others.
