Block sleeping tabs on specific sites

Computer and userIntune-readySleepingTabsBlockedForUrls_recommended

Supported on Microsoft Edge version 88, Windows 7 or later

155.0.4283.62

What it does

Define a list of sites, based on URL patterns, that aren't allowed to be put to sleep by sleeping tabs. Sites in this list are also excluded from other performance optimizations like efficiency mode and tab discard. If the policy 'SleepingTabsEnabled' (Configure sleeping tabs) is disabled, this list isn't used and no sites are put to sleep automatically. If you don't configure this policy, all sites are eligible to be put to sleep unless the user's personal configuration blocks them. Example value: https://www.contoso.com [*.]contoso.edu

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: SleepingTabsBlockedForUrlsDesc
