UserNeeds changes for IntuneL_ShowOutlookLoopComponentsForSupportedApps

Supported on SUPPORTED_Windows7 (defined in the Windows templates)

What it does

This policy controls whether Outlook displays Loop components that are supported by installed apps without requiring users to explicitly choose to load them. If you enable this policy setting, Outlook will automatically display Loop components in emails. This applies to all messages or specifically to messages that originate within the recipient's local tenant or organization. This might involve contacting servers used by the installed apps to retrieve Loop components. If you disable this policy setting, Outlook will not load content from external servers automatically, unless the sender is included in the Safe Senders list. Recipients will have the option to manually load Loop components from untrusted senders on a message-by-message basis. If you do not set this policy setting, Outlook will default to the “enabled" setting. Note: Loop components included in messages located in the Junk Mail folder will not load automatically, regardless of the policy setting specified. Loop components will only be shown for apps that are installed, ensuring security and a tailored experience in Outlook.

  • The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
  • Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
