Outlook 2013 Security Update for August 2018

A Security Update has been released for Outlook 2013. It provides “enhanced security as a defense in depth measure” as described in ADV180021 and is not related to a know security vulnerability. This update also contains additional fixes for 6 non-security issues.

Most notable fixes in this update;

  • After you use the “Rooms” button or the Room Finder add-in to change the conference room for a meeting, the “Location” of the meeting is not automatically updated to match the newly selected room.
  • Assume that you sign in to Outlook 2013 by using an account that doesn’t use modern authentication in Windows 10. The Security Support Provider Interface (SSPI) authentication prompt will sometimes appear behind other windows and be inaccessible from the keyboard. For more information, see KB4032226.
  • Dynamics CRM functionality is blocked unless you enable all roaming folder homepages by using the EnableRoamingFolderHomepages registry key.
