Outlook and Vista Freeze
Will Kennedy publishes an interesting post on Outlook and Vista freezing
The Short Story
We've released an update to Microsoft Office Outlook 2007 that will help to address some performance issues that are discussed in Knowledge Base Article 932086. You can find a description of the update and a link to the appropriate download page for your version of the update in Knowledge Base Article 933493.
(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.)
For the long story look at Wills blog. Very useful...
