M365 Changelog: Reminder: Microsoft Edge Legacy support to end on March 9, 2021

Petri Staff


MC229643 – 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 three months away, we strongly recommend that you build a transition plan to ensure that you have an up-to-date browser.

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.

The new Microsoft Edge is our best expression of a modern browser and is more secure than Chrome for your business on Windows 10. We understand that upgrading browsers isn’t as easy as flipping a switch. Here are some support options for you:

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.

What you need to do to prepare:

  • If you’d like help upgrading all your organization’s devices to the new Microsoft Edge, FastTrack can help with deployment and configuration at no additional charge for customers with eligible Microsoft 365 subscriptions.
  • Additional ways to upgrade to the new Microsoft Edge include:
  • 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.
  • If you’re a K-12 education customer, additional configuration is required.
  • You will want to notify your users to use the new Microsoft Edge or another supported browser. We have adoption materials available for user education.
  • You will also want to update any applicable user training and prepare your help desk. Microsoft Edge has browser policies available to aid with set up and help with the transition.
