Description
Lets you specify whether Microsoft Edge tabs wait to navigate until the browser downloaded the initial Enterprise Mode Site List. This setting is intended for the scenario where the browser home page should load in Internet Explorer (IE) mode, and it's important that it does so on browser first run after IE mode is enabled. If this scenario doesn't exist, we recommend not enabling this setting because it negatively impacts the performance of loading the home page. The setting only applies when Microsoft Edge doesn't have a cached Enterprise Mode Site List, such as on browser first run after IE mode is enabled. This setting works if 'InternetExplorerIntegrationLevel' (Configure Internet Explorer integration) is set to 'IEMode' and if either the 'InternetExplorerIntegrationSiteList' (Configure the Enterprise Mode Site List) or the 'InternetExplorerIntegrationCloudSiteList' (Configure the Enterprise Mode Cloud Site List) policies be enabled, where the list has at least one entry. The timeout behavior of this policy is configured with the 'NavigationDelayForInitialSiteListDownloadTimeout' (Set a timeout for delay of tab navigation for the Enterprise Mode Site List) policy. If you set this policy to 'All' and when Microsoft Edge doesn't have a cached version of the Enterprise Mode Site List, tabs delay navigating until the browser downloaded the site list. Sites configured to open in Internet Explorer mode by the site list load in Internet Explorer mode, even during the initial navigation of the browser. Sites that can't be configured to open in Internet Explorer, such as any site with a scheme other than http:, https:, file:, or ftp: don't delay navigating and load immediately in Microsoft Edge mode. When used with the 'InternetExplorerIntegrationCloudSiteList' policy, during first launch of Microsoft Edge, there is a delay because implicit sign in needs to finish before Microsoft Edge attempts to download the site list from the Microsoft cloud since this requires authentication to the cloud service. If you set this policy to 'None' or don't configure it and when Microsoft Edge doesn't have a cached version of the Enterprise Mode Site List, tabs navigate immediately and don't wait for the browser to download the Enterprise Mode Site List. Sites configured to open in Internet Explorer mode by the site list open in Microsoft Edge mode until the browser finished downloading the Enterprise Mode Site List. Policy options mapping: * None (0) = None * All (1) = All eligible navigations Use the preceding information when configuring this policy.
