Be aware that the update in the Microsoft Download Center applies to the Microsoft Installer (.msi)-based edition of Office 2016. It doesn't apply to the Office 2016 Click-to-Run editions, such as Microsoft Office 365 Home. (See What version of Office am I using?)
Improvements and fixes
Introduces a new group policy to block the external card loop feature. The following three states are created for the new policy to make sure that Outlook follows the policy setting:
- Don’t show automatically
- Only show automatically within tenant
- Always show automatically
Fixes an issue in which the Group Policy Editor (gpedit.msc) doesn’t load correctly after you create a new policy for the blocked external card loop.
