NEW DETAILS: Microsoft Edge Legacy support to end on March 9, 2021

As communicated in MC220490 (August ’20), Microsoft Edge Legacy desktop application support will end on March 9, 2021. After support ends, Microsoft Edge Legacy will not receive new security updates.

With March 9, 2021 only a month away, we strongly recommend that you build a transition plan to ensure that you have an up-to-date browser.

*NEW* To replace this out of support application, we are announcing that the new Microsoft Edge will be available as part of an upcoming Windows 10 cumulative monthly security update. When you apply this update to your devices, the new Microsoft Edge will be installed and the out of support Microsoft Edge Legacy will be removed.

Additionally, to continue using kiosk mode and avoid disruption to your kiosk scenarios, you will need to set up kiosk mode in the new Microsoft Edge.

Microsoft Edge Legacy desktop application

• Timing: End of support for the Microsoft Edge Legacy desktop app will occur on March 9, 2021.
• Action:
  • To continue using a supported browser, transition to the new Microsoft Edge.
  • To avoid disruption to your kiosk scenarios, you must additionally set up kiosk mode in the new Microsoft Edge.
  • If you are already using the new Microsoft Edge (and have set up any needed kiosk scenarios), no action is required.

How this will affect your organization:

After March 9, 2021, the Microsoft Edge Legacy desktop application will no longer be supported and will not receive new security updates. Move to the new Microsoft Edge before that date to ensure your organization is using an up-to-date browser.

*NEW* To replace this out of support application, we are announcing that the new Microsoft Edge will be available as part of the Windows 10 cumulative monthly security update—otherwise referred to as the Update Tuesday (or “B”) release—on April 13, 2021. When you apply this update, the out of support Microsoft Edge Legacy desktop application will be removed and the new Microsoft Edge will be installed. Read the announcement here.

This replacement will also occur if you apply the optional Windows 10 March Preview (or “C”) release.

To continue using kiosk mode and avoid disruption to your kiosk scenarios that were dependent on Microsoft Edge Legacy, you will need to set up kiosk mode in the new Microsoft Edge. If you do not set up kiosk mode in the new Microsoft Edge prior to applying the April’s Windows 10 Update Tuesday release, Microsoft Edge Legacy, and its kiosk mode, will no longer be available and you will experience a disruption in your kiosk scenarios. Please read this article detailing this transition.

What you need to do to prepare:

• The new Microsoft Edge is the planned update for Microsoft Edge Legacy; if you already have the new Microsoft Edge on your device(s), no action is required.

  • Download the latest package from the Microsoft Edge business download page and deploy to your environment.
• Change management:
