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.

可是我沒法找到這兩個更新：KB2817630和KB2817347，只有相近的更新包，如KB2817629，因而我將其刪除，重啓電腦，開outlook發現問題也可解決。
