A number of users are reporting performance issues with Outlook 2007
after installing update 2412171. 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)
*How Do I Fix it?*
At this time the only fix for it is to uninstall update 2412171, which
you can do in one of two ways:
1. Control Panel> Add/Remove Programs. In Windows 7 click "View
Installed Updates", find KB2412171 and uninstall it. In earlier
versions just make sure the "Show Updates" checkbox is checked and find
the update on the list. This is the best way to do it, as a general rule.
2. System Restore. If you can't remove the update individually, use
System Restore and restore back to the point before the update was
installed. See this article.
*Can I Help Solve It?*
The Outlook team is working hard to track down the cause of the issues
and it would be very helpful if you could provide a bit more
information. If you could reply in the forum thread, or e-mail me at
Email removed for privacy
<mailto:Email removed for privacy?subject=Outlook%202007%20and%202412171>
and post the following information it may help us track down the cause:
* Operating System you're using (Windows XP? Vista? Windows 7?)
* AntiVirus products you're using. (Norton? Microsoft Security
Essentials? NOD32?)
* How many and what kind of e-mail accounts you have. ("2 POP3
accounts with GMail" or "1 Exchange mailbox" or ?)
* Any 3rd party add-ins you have installed in Outlook. Xobni?
Other things?
* Do you have the Outlook Social Connector installed?
Thanks for your patience. Hopefully there will be a fix for this
problem soon!
