Step 8. Troubleshoot Microsoft Edge for Business Data Security

Troubleshooting app protection policies and app configuration policies (ACP) in Microsoft Intune can involve several different checks. This section consolidates the most common issues and resolutions so that you can quickly diagnose problems and restore your secure enterprise browser experience.

Successful app protection policy deployment relies on correct assignments, policy configuration, and platform dependencies. Use these quick checks before diving deeper into troubleshooting.

Quick checks

Use this list when users report issues with Microsoft Edge for Business:

• Verify policy assignment
  Ensure that app protection policies and app configuration policies are assigned to the correct user or device groups, and that Microsoft Edge for Business is in scope for those assignments.

• Review policy settings
  Confirm that the required settings for the selected security level are properly defined. Misconfigured data-transfer, clipboard, or sign-in settings often cause issues.

• Check Microsoft Edge version and OS support
  When Microsoft Edge crashes at launch or policies don't appear to apply, verify that both the OS version and Microsoft Edge version meet the minimum supported requirements.

• Validate user sign-in
  App protection policies only apply when a user signs into Microsoft Edge for Business using their Microsoft Entra ID work account. Personal or local accounts won't receive policy enforcement.

• Understand unmanaged share behavior
  On mobile devices, the system share extension can bypass some restrictions unless the device is managed. In these situations, Intune encrypts corporate data before it leaves the app.

• Check app requirements

  • Microsoft Authenticator is required when App-based Conditional Access is enabled.
  • Company Portal (Android) is required for APP enforcement even if the device isn't enrolled.

• Confirm the configuration channel
  If ACP settings aren't applying, verify that you're using the correct configuration channel (managed apps vs. managed devices) and that identifiers, configuration keys, and JSON syntax match publisher documentation.

• “Sign in with your work account” message
  This usually appears when the user signed in using an account that isn't targeted by the app protection policy or when the enrollment method doesn’t match what the policy requires.

Policy deployment issues

Settings Catalog policies not applying

• Likely cause: Device enrollment or sync issues
• How to fix:
  • Verify device enrollment status and force sync from Company Portal

App protection policies not enforcing

• Likely cause: User is signed into Edge with a personal profile
• How to fix:
  • Confirm user signed into Edge with Entra ID account

App configuration policies showing as failed

• Likely cause: JSON syntax errors or invalid configuration values
• How to fix:
  • Validate JSON configuration syntax and policy values

Conditional Access blocking unexpectedly

• Likely cause: Device compliance evaluation failure
• How to fix:
  • Check device compliance status and reevaluate policies

Policy conflicts between security levels

• Likely cause: Users or devices receiving multiple overlapping level assignments
• How to fix:
  • Review group membership and policy assignments for overlaps

Platform-specific issues

Windows: Edge security baseline not applying

• Likely cause: Unsupported Windows build or Microsoft Edge version
• How to fix:
  • Confirm the device is on a supported Windows 11 build.

Windows: Application Guard not working

• Likely cause: Feature not enabled or missing virtualization support
• How to fix:
  • Enable Windows Defender Application Guard.

iOS/Android: APP policies not enforcing on BYOD

• Likely cause: User not enrolled in MAM or hasn’t completed the Company Portal/Authenticator flow
• How to fix:
  • Guide the user through MAM enrollment.

iOS/Android: ACP settings not applying

• Likely cause: Outdated Edge mobile app
• How to fix:
  • Update to the latest Microsoft Edge mobile version.

macOS: Settings Catalog policies failing

• Likely cause: macOS version below minimum requirements
• How to fix:
  • Verify minimum supported macOS versions for the targeted policies.

User experience issues

Users at Level 3 reporting blocked websites

• Likely cause: Restrictive URL filtering
• Recommended action: Review and expand allowed URLs through change process

Mobile users unable to copy/paste

• Likely cause: App Protection Policy restrictions
• Recommended action: Validate policy settings match intended restrictions

Authentication prompts too frequent

• Likely cause: Aggressive Conditional Access settings
• Recommended action: Review session timeout and reauthentication policies

Features missing or disabled

• Likely cause: Level 3 feature restrictions
• Recommended action: Confirm user assigned to correct security level group
