This issue has been popping up on many sources starting with Twitter last evening. As we all know Microsoft pushes software updates on “Patch Tuesday.” Well today is Wednesday and here we all are dealing with another set of bad patch updates.
The patch associated with KB2817630, which is a general update for Office 2013, contains a bug that results in a broken navigation pane inside Microsoft Outlook 2013. The resolution to the issue is fairly straight forward in that you simply uninstall the aforementioned hotfix and reboot your machine. Imagine doing that across an enterprise. In the middle of hump day.
Additional issues have been identified with the hotfixes released on Sept 10 and associated with the following KB’s:
- KB 2810009 – Access 2013
- KB 2760411 – Office 2007
- KB 2760588 – Excel 2007
- KB 2760583 – Excel 2007
You can hang this in your office:
Microsoft has released a post on their Microsoft Office Updates blog on TechNet detailing the specifics around the issue with the Outlook Nav Pane issue. The issue is described by Microsoft with the following:
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.
Some quick notes from the post:
- The issue only affects MSI-based installations of Office or Outlook 2013. These are the installations typically found in business environments and usually licensed under volume license agreements.
- The issue seems to only appear if you have either the September Public Update -OR- the August Cumulative Update installed. Not both. If you have both installed the versioning issue causing the problem should not occur.
- There are reports that the updates may need to be removed multiple times in order to resolve the issue. This is a little odd but when you uninstall make sure to go back and check for the hotfix again as it may still be present.
