Force Web Apps to open in the Managed Browser with hybrid SCCM/Intune
Currently in Intune Standalone it is possible to create an external link and enable the option "Require a managed browser to open this link (Android and iOS only)". For the hybrid SCCM/Intune it is not possible yet. This feature would be nice to add to hybrid SCCM/Intune
You actually can force web apps to open in the Intune Managed Browser. There’s no checkbox in the SCCM console, but changing the protocol of the web app’s URL from “http” to “http-intunemam” or from “https” to “https-intunemam” prevents it from being opened in a non-managed browser.
