Specify the number of days that a site remains on the local IE mode site list
Verified with Microsoft Edge 152.0.4191.53 — updated on July 10, 2026

Path in the GPO console
Computer Configuration\Administrative Templates\Microsoft Edge User Configuration\Administrative Templates\Microsoft Edge Description
If the 'InternetExplorerIntegrationReloadInIEModeAllowed' (Allow unconfigured sites to be reloaded in Internet Explorer mode) policy is enabled or not configured, users will be able to tell Microsoft Edge to load specific pages in Internet Explorer mode for a limited number of days. You can use this setting to determine how many days that configuration is remembered in the browser. After this period has elapsed, the individual page will no longer automatically load in IE mode. If you disable the 'InternetExplorerIntegrationReloadInIEModeAllowed' policy, this policy has no effect. If you disable or don't configure this policy, the default value of 30 days is used. If you enable this policy, you must enter the number of days for which the sites are retained on the user's local site list in Microsoft Edge. The value can be from 0 to 90 days.

BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
