Default cookies setting

Computer and userIntune-readyDefaultCookiesSetting

Supported on Microsoft Windows 7 or later

155.0.8059.85

What it does

Unless the RestoreOnStartup policy is set to permanently restore URLs from previous sessions, then setting CookiesSessionOnlyForUrls lets you make a list of URL patterns that specify sites that can and can't set cookies for one session. Leaving the policy unset results in the use of DefaultCookiesSetting for all sites, if it's set. If not, the user's personal setting applies. URLs not covered by the patterns specified also result in the use of defaults. While no specific policy takes precedence, see CookiesBlockedForUrls and CookiesAllowedForUrls. URL patterns among these 3 policies must not conflict.

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: DefaultCookiesSetting
