This article describes update 5002574 for Microsoft Outlook 2016 that was released on April 2, 2024. 

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.
