Goodbye Internet Explorer and the original Edge browser

Office 365 Blog

Microsoft Internet Explorer, originally released in 1994, getting to its last version, number 11, in 2013, is finally being put to pasture.

Also, the original Microsoft Edge, which has an icon like this , is being replaced and will no longer receive security updates.  That browser is now known as Microsoft Edge Legacy.

Important Dates

9 March 2021

Microsoft Edge Legacy desktop app will not receive new security updates.

2 April 2021

Microsoft will remove Internet Explorer 11 and Microsoft Edge Legacy browsers from the list of supported browsers for the Business Central modern clients.

17 August 2021

Microsoft (formerly Office) 365 will no longer support IE11.

This means that after the above date, customers will have a degraded experience or will be unable to connect to Microsoft 365 apps and services on IE 11. For degraded experiences, new Microsoft 365 features will not be available or certain features may cease to work when accessing the app or service via IE 11.

By the dates listed above, you should no longer access Microsoft 365 apps and services using IE 11, but we want to be clear that IE 11 is not going away, your own legacy IE 11 apps and investments will continue to work.

In this moment of bridging between modern and legacy apps, many customers may feel there is no choice but to rely on a two-browser workaround of using IE 11 alongside a modern browser. However, with the new Microsoft Edge and Internet Explorer mode, you do not need an awkward workaround of one browser for some apps and another for other apps. You can standardize on one browser and seamlessly experience the best of the modern web in one tab while accessing a business-critical legacy IE 11 app in another tab – all housed within the new Microsoft Edge.  Apps and sites created for Microsoft Edge Legacy will continue to work in the new Microsoft Edge.
