This article provides a collection of resources to help you understand potential issues around Microsoft Office Outlook 2007 performance, and to assist you in configuring features for best performance in your organization.

To help ensure that Office Outlook 2007 is performing well, install the most recent update for Office Outlook 2007. For a description of the update and links to the update, see Microsoft Knowledge Base article 933493: Description of the update for Outlook 2007: April 13, 2007 (https://go.microsoft.com/fwlink/?LinkId=90637).

Cached Exchange Mode

To improve Office Outlook 2007 performance on highly latent networks, we recommend that users of Outlook 2003 or Office Outlook 2007 use Cached Exchange Mode, where users work with a local cache of their mailboxes. If Cached Exchange Mode is not possible, then we recommend that online users on highly latent networks turn off the To-Do Bar feature to eliminate additional server calls.

For information about how to configure Cached Exchange Mode, see Configure Cached Exchange Mode in Outlook 2007.

For information about how to turn off the To-Do Bar feature, see Turn the To-Do Bar on or off (https://go.microsoft.com/fwlink/?LinkId=108197).

Windows Desktop Search and Outlook 2007

There are many ways to configure Windows Desktop Search and Instant Search that can help reduce indexing time or improve performance in other ways. For details about configuration options, see the following articles:

Changed features: impact and support documentation
