Default Adobe Flash setting (obsolete)

Computer and userIntune-readyDefaultPluginsSetting

Supported on Microsoft Edge version 77-87, Windows 7 or later

155.0.4283.62

What it does

OBSOLETE: This policy is obsolete and doesn't work after Microsoft Edge 87. This policy doesn't work because Flash is no longer supported by Microsoft Edge. 'PluginsAllowedForUrls' (Allow the Adobe Flash plug-in on specific sites) and 'PluginsBlockedForUrls' (Block the Adobe Flash plug-in on specific sites) are checked first, then this policy. The options are 'ClickToPlay' and 'BlockPlugins'. If you set this policy to 'BlockPlugins', this plugin is denied for all websites. 'ClickToPlay' lets the Flash plugin run, but users click the placeholder to start it. If you don't configure this policy, the user can change this setting manually. Note: Automatic playback is only for domains explicitly listed in the 'PluginsAllowedForUrls' policy. To turn automatic playback on for all sites, add http://* and https://* to the allowed list of URLs. Policy options mapping: * BlockPlugins (2) = Block the Adobe Flash plugin * ClickToPlay (3) = Click to play Use the preceding information when configuring this policy.

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.
The generated payload is incomplete because one or more ADMX element values were not supplied: DefaultPluginsSetting
