Microsoft says a recent patch for Outlook 2007 caused slow performance and problems with third party e-mail services. The company has withdrawn the update KB2412171 from its Microsoft Update service. Microsoft recommends that customers who have installed it and encountered problems uninstall the patch. The update prevented Gmail users from connecting to Gmail s mail servers if the Outlook Secure Password Authentication (SPA) option was enabled, and broke Auto Archiving for IMAP, POP3 and Oulook Live Connector Accounts.
