Policy
Control which apps cannot be opened in Microsoft Edge sidebar
Microsoft Edge
Policy overview
Key metadata and intent for this policy.
Supported OS tags: Windows7
Define a list of sites, based on URL patterns, that cannot be opened in sidebar. If you don't configure this policy, a user can open any app in sidebar. If the 'HubsSidebarEnabled' (Show Hubs Sidebar) policy is disabled, this list isn't used and no sidebar can be opened. For detailed information about valid url patterns, see https://go.microsoft.com/fwlink/?linkid=2281313. Note: A blocklist value of '*' means all apps are blocked unless they are explicitly listed in the 'EdgeSidebarAppUrlHostAllowList' (Allow specific apps to be opened in Microsoft Edge sidebar) policy. Starting in Microsoft Edge version 149, the 'Microsoft365CopilotChatIconEnabled' (Control whether Microsoft 365 Copilot Chat shows in the Microsoft Edge for Business toolbar) policy controls the display of Copilot in the sidebar. Example value: https://www.contoso.com [*.]contoso.edu
