Outlook 2013 Folder Pane Disappears After Installing September 2013 Public Update

Update: http://blogs.technet.com/b/office_sustained_engineering/archive/2013/09/26/september-2013-out-of-band-office-release.aspx

This issue has been corrected with an update described in the link above, and has been delivered as an automatic update via Microsoft Update. If you are still experiencing this issue, please re-run Microsoft Update, check for updates, and ensure you are on the latest versions of each package.

Shortly after publishing the September Public Update, we received notifications of a potential issue with Outlook 2013 after installing the non-security update KB2817630. Based on those reports we immediately removed the patch from Microsoft Update - within 3 hours of its release. If you haven’t already downloaded or installed the patch, you will not have these problems or be offered the problematic patch.

In contrast to what has been reported, MS13-068 is not the cause nor is it affected by this issue.

This blog post will describe the problem and explain how to fix it.   It also reminds users what to do if a Patch Tuesday update causes issues.

We are very careful with Public Updates given their wide and rapid proliferation. We regret any inconvenience caused by this update, and we are hopeful that this information can help you restore productivity in Outlook products.

Understanding the issue

Due to a version incompatibility between outlook.exe and mso.dll, a mismatched reference to a data structure causes the “Minimize” button in the navigation
pane to render incorrectly, typically extremely large to the point that the navigation pane is "invisible" to the user. The issue only manifests when incompatible versions of outlook.exe and mso.dll exist on the system.

 

If both versions are earlier (lower) than 4535.1000, or both versions are later (higher) than 4535.1000, the problem does not manifest. If one file is updated but the other is not, the problem is evident. The incompatible state is created by installing either the September Public Update OR the August Cumulative update, but not both. Users of MSI-based products that have automatic updates enabled are those that are most likely to have encountered the issue.

Office 2013 Click-to-Run products are not affected.

Office 2013 Versions Affected

  • Office 2013 Standard
  • Office 2013 Professional Plus

Said differently, only MSI installations of Office or Outlook 2013 are affected. These are volume-license installations typically found in businesses that
purchase licenses in volume.

Each version of Office installed, such as viewers, standalone client products, Office suites with MSI-based installations, etc., will receive the update. We have
seen reports of some users needing to remove the update 2 or 3 times. This is because the system has product ID’s for multiple installations of MSI-based
Office products.

Office 2013 Versions that are NOT affected:

  • Office 2013 Home & Student
  • Office 2013 Home & Business
  • Office 2013 Professional
  • Office 365 Home Premium
  • Office 365 Professional Plus
  • Office 365 University
  • Office 365 Small Business Premium
  • Office 365 ProPlus
  • Office 365 Enterprise

How to fix affected installations:

Two updates can get a user into this state. Installing the September Public Update delivers an updated version of mso.dll without updating outlook.exe, resulting in the incorrect user interface.

  • If you have Automatic Updates enabled, visit the Add Remove Programs feature of your Windows Installation, and uninstall KB2817630. Close Outlook and restart.
  • If you have installed the August Cumulative update (which you must do manually), removing KB2817347 will correct the issue. From the Add Remove Programs feature, select KB2817347 from the list and select “Uninstall.” Close Outlook and restart.
  • If you have BOTH Updates installed, the problem is not evident. The issue only manifests when one of the updates has been installed. If you have updated to the September Public Update and you want to roll forward, install the August Cumulative update, KB2817347.

We are also working on re-publishing the September Public Update with the correct versions of both mso.dll and outlook.exe to ensure users with automatic updates enabled will receive the correct fix. We will update this blog with further information as our schedule develops.

How to obtain support:

When you encounter trouble with a Public Update, you can always contact us at http://support.microsoft.com. You can call Microsoft directly at 1-866-234-6020. Alternatively, please contact our community network at Microsoft Community or visit Microsoft Support for access to extensive online self-help resources.

  • Glad to hear "only" the corporate versions were affected, lol.

    Curious though...presumably many of us in corporate are using WSUS to patch PCs. If I decline the current patch, will the fixed revision show in WSUS or will it too be declined?

    Thanks

  • My outlook state is "Not OK" due the versión number of mso.dll and outlook.exe

    I proceeded  to uninstall KB2817630 but the problem persists.

    In the list of updates KB2817347 not exist.

    I need "Folder Pane" to move mails to local folders...

    I need a Fix...soon...

  • Luis, did you restart outlook after removing the KB? Can you see if the KB is still installed for other products?

  • Applied the hotfix to correct the KB2817630 problem and now when printing an email two new lines are added to the header of the email:

    Sensitivity: Male

    Flag Status: Red

    Don't see a way to remove them from printing.

  • Microsoft: Please consider releasing Office system Cumulative Updates to MU/WSUS as an optional update category.  Security Updates often break functionality that is only restored via a Cumulative Update.  By allowing admins to fix the issue using the same method they deployed the Security Update would go a long way to increasing admin satisfaction.

  • completely same with @LuisCo

    I uninstalled KB2817630 and folder pane is still missing and update KB2817347 not exist.

    Before you asked it I'll tell: Yes I restarted both Outlook and computer several times and nothing fixed.

    Do you have any other solution than restart something?

    Also KB2810009 update still fails...

  • Thanks I removed KB2817630 and restarted...  all fixed.

  • Security Update for Microsoft Office 2013 (KB2810009) 64-Bit Edition

    Download size: 3.5 MB

    You may need to restart your computer for this update to take effect.

    Update type: Important

    A security vulnerability exists in Microsoft Office 2013 64-Bit Edition that could allow arbitrary code to run when a maliciously modified file is opened. This update resolves that vulnerability.

    More information:

    support.microsoft.com/.../2810009

    I work indirectly for MS, I have had a problem with the above update. This has been with drawn. But my machines still want to install it. It has coursed my VPN not to work. But MS helpdesk can't fix this issue. In fact they have made it worst. Three days now VPN not working.

  • uninstalled KB2817630, problem persists...

    my Office 2013 early adopters hate me

  • I had the same problem as LuisCo and Alexandar.  After uninstalling KB2817630 and rebooting my machine the problem persisted.  Eduardo's post pointed me in the right direction... I found 4 additional installations of KB2817630.  After removing all 4 and rebooting the problem is now resolved.

  • I have Office 2013 Professional Plus. My Windows did an automatic critical update this morning. After the update, none of my Office programs would open. They all said they were missing shared files and I needed to reinstall.  I restored my computer to a few days ago and everything works fine again. EXCEPT... Windows wants to install these critical updates. I shut off the automatic updates, but am not sure what to do.  I am 64 bit.

  • The patch is removed from Windows Update, but it is not declined/expired on WSUS/SCCM. Why is that?

  • With the new MS Update this week to Windows 7, all of my documnet icons were changed to Windows 2010 Office and I cannot access my documents unless I pay Microsoft for Office 2010. Two weeks ago, because of Win7 updates, my log-in service failed twice and I had to restore my ssytem twice. I am outraged at MIcrosoft for causing me so much pain and suffering and I think that your company should make this up to me!

  • What about the three Office 2007 patches that are broken?  Any word on when they will be pulled and new patches added?

  • Microsoft Office 2013 update (KB2810009) 64-bit edition has finally installed successfully. This only happed in the past two hours while I was away from my computer. I shutdown and restarted for the update to be successful.

    This cleared the queue for any additional pending updates.
