Outlook 2013 Folder Pane empty / blue / gone / no folders after September Office Update caused by KB2817630 patch

Recently, opening my Outlook 2013, the folder pane was empty. Indeed, it looked not really to be empty. It was filled with blue color and the was some mouseover effect happening moving the pointer over it.

How-i-fixed-it:
It turned out, that the September update of Office Software can cause this issue in case a certain combination of Outook.exe and mso.dll happens. It's the KB2817630 patch causing the problem in case the August Cumulative update is NOT installed on the Computer.

Here's what the TechNet blog says:
"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."

It only happes to:

Office 2013 Standard

Office 2013 Professional Plus

Here's a good description, how to fix it: http://blogs.technet.com/b/office_sustained_engineering/archive/2013/09/11/outlook-folder-pane-disappears-after-installing-september-2013-public-update.aspx

Where can you find the Outlook.exe and mso.dll Version Information?
Go to File -> Office Account -> Info about Outlook
