ExternalProtocolDialogShowAlwaysOpenCheckbox is not working on Edge
HI Kelly_Y, Last time I observed it working was in version 83.
As Silverlight is getting obsolete, I have created a windows custom protocol handler which was previous handled by Silverlight application. Now, when a User clicks on a button my custom protocol will be invoked but we are getting a popup every time with open/cancel buttons to perform the action.
Microsoftanilrepala Hi! The policy was restricted to only work from secure (i.e. https) pages. I believe the change was made around Version 83. Can you confirm if you are using https:// links? If so, let us know and we'll loop in the GPO team. Thanks!

Kelly_Y Hi, We are using the only HTTP:// links. As per your comments, we can't surpass the pop-up for HTTP:// links but can we make the 'Open' button as default instead of the 'Cancel' button?

anilrepala505 For security reasons (to avoid gesture hijacking attacks), it is important that the default button remain Cancel. However, administrators are able to preapprove Origin/Protocol combinations using the AutoLaunchProtocolsFromOrigins policy, and non-secure HTTP origins may be specified there at the administrator's discretion.
