The February Cumulative Update for Outlook 2007 has been released – it contains a significant number of new performance-focused improvements. 

The Outlook team say they especially focused on the areas of starting up and shutting down Outlook, switching between folders with large numbers of messages, calendar reliability and consistency, and general responsiveness of the application when performing common tasks around managing your e-mail, calendar, and other information. In short, they believe your daily experience with Outlook will be greatly improved with the installation of this Cumulative Update.

    I can recall blogs complaining about these very issues upon Outlook 2007’s release.

    Guess it’s finally, after several years, out of Beta, and worth a look again.

    Apparently Office goes by the “wait for SP2” rule.

    The performance gains you allude to are not referenced in the included information at the page of the download link. Specifically they say to ONLY install it if you have the specific issues mentioned. I don’t have any of those issues; however, the slowness in general of opening large things would be great if it is included.

    I’m hesitant to throw a “hotfix” (not an update) on a production workstation when it involves such a critical piece of software. Going to have to lab it first. Thanks for the heads-up.
