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.
