(Users of the Business Contact Manager features of Outlook should see the note at the end of this post about a separate update that should be installed first.)
The Long Story
We’ve been investigating some reported performance problems with Microsoft Office Outlook 2007 for some time. Our investigations revealed that these specific performance problems affected users who had large mailbox files (.pst and .ost files) stored on their computers.
As part of our continued effort to improve our customers’ product experiences, on Friday we released an update to Microsoft Office Outlook 2007 that addresses these specific performance problems. You can find a link to the update below (or above, for that matter).
Some of these performance problems have been discussed in external blogs and other forums written by our customers. We certainly appreciate learning about everyone’s individual experiences with the product. We hope that this update will address many of the performance problems that people have noticed. As of today, the update has already been downloaded by more than 12,000 times by people around the world.
This particular update includes several performance improvements rolled into one patch. It’s designed to improve the general responsiveness of Outlook during common operations including reading, moving, deleting, and downloading e-mail messages for users who have large mailbox files. For those out there who care about the technical details, there are two specific changes are worth mentioning:
It’s important to note that these changes do NOT change the format of either .pst or .ost files. There is no need to rebuild these files, and files created with this updated version of Outlook are backwards-compatible with previous versions of Outlook.
Customers who install this update may notice generally improved performance and responsiveness when Outlook is reading or writing data. Examples of these improvements include:
This update was specifically designed to address performance problems which occur with large mailbox files, but you may see an improvement in performance with this update even if your mailbox file isn’t “large” due to the specific data in your mailbox. Our efforts in analyzing the performance of Outlook are continuing, even after these changes.
As I mentioned above, we appreciate hearing about the experiences of our customers and we certainly hope that this update improves your experience with Outlook 2007.

I do hope that this update improves your experience with Outlook 2007!
