Trigger to apply junk email list settings

UserNeeds changes for IntuneL_JunkMailImportList

Supported on SUPPORTED_Windows7 (defined in the Windows templates)

What it does

This policy setting allows you to trigger the activation of other junk e-mail policy settings. If you enable this policy setting, you will trigger the activation of other junk e-mail policy settings. For example, if you configure the "Specify path to Safe Senders list" policy setting, the specified Safe Senders list is not imported by Outlook unless you also enable the "Junk Mail Import List" policy setting. If you disable or do not configure this policy setting, you will not trigger the activation of other junk e-mail policies.

  • 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.
