Description

By default, Tasks, Appointments, Journal Entries, and Contacts hide the controls in the Outlook user interface used for linking related contacts. When you enable this setting, the linking controls appear in Outlook. You might choose to enable this setting if your users rely on contact linking - for example, to track partners who attend appointments together or to track ways in which contacts are related to each other.

Export Builder

BETA

Configure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.

These exports write the registry — this is not a managed GPO.
