Botched patch messes up Outlook 2007

Microsoft pushed a nonsecurity patch on December 14 that slows down Outlook 2007. There's still no fix

As part of the record-breaking Dec. 14 Black Tuesday patchfest, Microsoft released a "nonsecurity" patch for Outlook 2007 called KB 2412171. Billed as a "stability and performance" enhancement, the patch has, uh, yet to live up to its billing. Gregg Keizer details the problems in his Computerworld article.

Microsoft has owned up to all of these glitches:

  • A lengthy delay -- some say a minute or longer -- when switching between folders, particularly folders located in different message stores.
  • Auto Archiving doesn't work at all.
  • When sending or receiving mail, accounts that use Secure Password Authentication may not work at all. Ben Schorr's OfficeForLawyers website describes errors on "Outlook Anywhere (RPC over HTTP) connections that use NTLM authentication. In particular this has been affecting a lot of Gmail users who check their Gmail with Outlook."

Microsoft pulled the KB 2412171 patch on Dec. 16. As of this writing, it's still unavailable -- a good thing because anyone who had the misfortune of installing KB 2412171 is now being instructed by Microsoft to remove it.

The Microsoft Outlook blog gives a detailed explanation, which varies in some details with Ben Schorr's description. Interestingly, the official blog entry says that Office 365 beta testers don't have to uninstall the botched patch, but Office 365 testers may have to manually turn off Secure Password Authorization on some email accounts.

I'm assured that, appearances to the contrary, Microsoft does test these patches before pushing them out for Automatic Update.

There's no word on when a fixed patch may become available.
