Outlook 2007 and Update 2412171

Updated: 1/11/2011 5:45PM MST

A number of users are reporting performance issues with Outlook 2007 after installing update KB2412171.  Possible symptoms include:

  • Slow performance when changing folders, especially folders that are in different message stores. 
  • Loss of Archive functionality
  • Errors receiving mail on accounts that use Secure Password Authentication (SPA) or 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.

How Do I Fix it?

Today Microsoft released an fix for the KB2412171 problem. It will be automatically installed by Windows Update if you let it, but if for some reason you don't have Automatic Updates running try going to http://update.microsoft.com and let the updater download and install the fix.

Thanks for your patience!
