If your organization uses allowed or blocked sites list for Microsoft Edge, your users will hit the following screen when they visit websites that are not allowed or blocked from the MAM protected applications like outlook, teams, etc.

This is very annoying for end-users all the time for such blocked or not allowed websites.

Inorder to improve the end-user experience, there are some configurations we can define in Intune app configuration settings.

Before Ignite 2019, there was only one setting that you can configure for Edge browser for blocked sites:

Key Value
com.microsoft.intune.mam.managedbrowser.AllowTransitionOnBlock True allows Microsoft Edge to transition users to their personal context to open blocked sites.
Block prevents Microsoft Edge from transitioning users. Users are simply shown a message stating that the site they are trying to access is blocked.

After Ignite 2019, Microsoft introduced new configuration changes to Edge mobile browser for iOS and Andriod which will now provide great end-user experience when browsing any blocked sites in private mode.

We can now create/update app configuration policy for edge browser (iOS and Andriod) to automatically open any blocked sites in private mode (soft transition) without showing the site blocked prompt:

com.microsoft.intune.mam.managedbrowser.openInPrivateIfBlocked with value true

When users browse any blocked websites in private mode, they can now see a snack bar display at the bottom of the browser that they are running in private mode.

This behavior can now be controlled with time (in seconds) as well.

com.microsoft.intune.mam.managedbrowser.durationOfOpenInPrivateSnackBar with value 10

if you do not configure this setting then users will see a snack bar few sec in-private browsing mode.

If you define the setting with 10 then users will see a snack bar for about 10 sec and it will disappear.

Summary of configuration options when users browse blocked websites:

Key Value
com.microsoft.intune.mam.managedbrowser.AllowTransitionOnBlock True allows Microsoft Edge to transition users to their personal context to open blocked sites.
Block prevents Microsoft Edge from transitioning users. Users are simply shown a message stating that the site they are trying to access is blocked.
