On Tuesday, December 14, we released an update (KB2412171) for Microsoft Outlook 2007. We have discovered several issues with the update and want to inform you about problems you might encounter and what corrective steps we recommend. As of December 16, this Outlook 2007 update has been removed from Microsoft Update.
This Outlook 2007 update was distributed via Microsoft Update. Many of you receive updates automatically and if you installed the update between Tuesday, December 14, and Thursday, December 16, it is likely that you are affected.
The three issues identified in the December 2010 update for Outlook 2007 are as follows:
If you are experiencing any of the listed issues with Outlook 2007, we recommend that you uninstall the December 2010 update by doing the following:
Uninstalling KB2412171 on Windows 7 or Windows Vista
Uninstalling KB2412171 on Windows XP
Note for Office 365 Beta customers: You do not need to uninstall this update. The listed folder switching and AutoArchive issues do not apply because Office 365 accounts are Exchange Server accounts. However, the issue with SPA when connecting to non-Exchange Server accounts that don’t support SPA does apply. In this case, turn off the SPA option by doing the following:
We apologize to our customers for not discovering these issues before releasing the update and for any inconvenience we have caused. We know that you rely on Outlook and for that reason, we thoroughly quality test every update. We failed to meet our own and our customers’ expectation for quality with this update release. We are working to fix these issues and will post a release date for those fixes, and link to download them, as soon as that information is available.
We value the trust that you place in our software, and we are actively working to resolve these issues.
The Outlook Team
there's very recent Outlook 2007 update in January that makes impossible reading messages from archive file folder if it contains more than 255 items. (sic!)
I have 200MB folder with 111 messages which opens
and another 7MB only with 314 messages and it does not open, displaying:
'The messaging interface has returned an unknown error...' Suggestion to restart Outlook is very naive, indeed.
MS Update has just offered me KB2412171 again. The link to "more information" takes me to MS Support at support.microsoft.com/.../2412171, which seems to suggest that this is a later version of that nightmare update. I cannot believe that they would issue this under the same code number, especially without explicitly stating that the flaws in the earlier release have been fixed. I have no intention of installing it before I see confirmation that it will not cause me the same problems which I struggled with back in December. As for thanking the Outlook team for this article, my searches on 18th December found nothing pertinent from them and I had to rely on helpful posts elsewhere; my thanks go to those more knowledgable users who found the uninstall solution and put it out there to help everyone, including amateurs like me.
This update broke the Outlook auto-configure settings in the Office 2007 Transform (ORK) we used to install Office 2007. When a user (new profile) opens Outlook it uses the "userprincipalname" now instead of the "samaccountname" from AD. We use CAC's for Authentication and the Card's EDIPI is in the userprincipalname and Exchange can't resolve it to an account. When we uninstall the KB2412171 update the Outlook auto-configure works again for a new user profile on the system. Your JAN update to the update does not fix the problem - we tested it.
I removed the Update for Microsoft Outlook 2007 (KB2412171) yesterday but it auto re-installed this morning… now my computer is freezing up again people. Can you either fix this security update or remove it from Microsoft auto updates. I really don’t want to turn it off because of important security updates I might need. If anyone has other suggestions, please post them.
Outlook forced me into updating the connector before it let me open my mail, since that point it has been failing with an error 0x80040126 on sending any outbound emails (inbound receiving works fine). I have been completely frustrated by this for weeks. After trawling suggestions for resolving this, with many false paths, I have seen this forum. I have removed the patch KB2412171 discussed with no joy. If anyone has any suggestions then I would be most grateful.
Uninstalled the first version of this update, but Archiving functions did not return. Performance did improve. I have succesfully installed the new version of this update, but Archive functions did not return. Anyone know how to fix this? I followed the instructions to install on Microsoft's web site. The time/date stamp on the Outlook.exe file does not change after installation??
It took me better than two weeks of frustration trying to get Outlook to work properly...to no avail. Then I searched on the web and found many others with the same problem, leading me to this site. I removed the update as directed. Outlook was back to normal. Great!
However, the auto update wants to install the same #$@! item again (same number). I turned off the auto-update feature. This a preventable situation, MS team. We spend good money to have legit software and now can't trust Microsoft to maintain their own packages? Bad dog...no biscuit! When can I turn on the auto update? When will you remove this "bungled" patch and prevent it from re-installing? More to the point, 100 patches can quietly occur and no problems. Kudos! With this one, we (the consumer) lose confidence in you and ask what other option do you have to notify us or let a system message occur during a patch Tuesday to correct a known major flaw?
Fixes for issues with December Update for Outlook 2007 have been released.
For the last 2 days, i have been experiencing serious and frustrating problems with outlook 2007. Just found this blog and then remove kb2412171 and install the new version January 10, 2011. But it hasn't solve any oof the problems. I do use POP3 type of account. What else can i do? it is really frustrating. The major issues is the navigation between folders and the loading of message's content. it takes forever to load and most of the time i have to restart the computer to refresh the whole thing.

We are using Outlook 2007 with the rest of the office suite at 2003 (due to custom templates that won't work with 2007), we tested this patch for issues before rolling out via WSUS. We have now found that some users cannot use the search box as it causes Outlook to stop responding and needs restarting, however, using ctrl+shift+f seems to be ok. Please look into this Microsoft.
Thanks! I can use it now!
Its nearly nearly half way through the year and this problem still does not appear to be fixed.
Sometimes the patch does not appear in View install updates and I have to completely uninstall Office.
Any just you can create a program to remove this patch.
